The answer to the question "is it a liturgical abuse to receive communion in the hand" is: yes and no.
Yes, it is an abuse to receive communion in the hand in those jurisdictions where no indult has been granted, and, no, it is not an abuse to receive communion in the hand in those jurisdictions where an indult has been granted. In the interview linked in the question, the document Memoriale Domini is mentioned. This is the relevant ecclesial document for this question. It says
When therefore a small number of episcopal conferences and some individual bishops asked that the practice of placing the consecrated
hosts in the people's hands be permitted in their territories, the
Holy Father decided that all the bishops of the Latin Church should be
asked if they thought it opportune to introduce this rite. A change in
a matter of such moment, based on a most ancient and venerable
tradition, does not merely affect discipline. It carries certain
dangers with it which may arise from the new manner of administering
holy communion: the danger of a loss of reverence for the august
sacrament of the altar, of profanation, of adulterating the true
Three questions were asked of the bishops, and the replies received by
12 March 1969 were as follows:
- Do you think that attention should be paid to the desire that, over and above the traditional manner, the rite of receiving holy communion
on the hand should be admitted?
Yes, but with reservations: 315
Invalid votes: 20
- Is it your wish that this new rite be first tried in small communities, with the consent of the bishop?
Invalid votes, 70
- Do you think that the faithful will receive this new rite gladly, after a proper catechetical preparation?
Invalid votes: 128
From the returns it is clear that the vast majority of bishops believe
that the present discipline should not be changed, and that if it
were, the change would be offensive to the sentiments and the
spiritual culture of these bishops and of many of the faithful.
Therefore, taking into account the remarks and the advice of those
whom "the Holy Spirit has placed to rule over" the Churches, in
view of the gravity of the matter and the force of the arguments put
forward, the Holy Father has decided not to change the existing way of
administering holy communion to the faithful.
The Apostolic See therefore emphatically urges bishops, priests and
laity to obey carefully the law which is still valid and which has
again been confirmed. It urges them to take account of the judgment
given by the majority of Catholic bishops, of the rite now in use in
the liturgy, of the common good of the Church.
Where a contrary usage, that of placing holy communion on the hand,
prevails, the Holy See—wishing to help them fulfill their task, often
difficult as it is nowadays—lays on those conferences the task of
weighing carefully whatever special circumstances may exist there,
taking care to avoid any risk of lack of respect or of false opinions
with regard to the Blessed Eucharist, and to avoid any other ill
effects that may follow.
In such cases, episcopal conferences should examine matters carefully
and should make whatever decisions, by a secret vote and with a
two-thirds majority, are needed to regulate matters. Their decisions
should be sent to Rome to receive the necessary confirmation,
accompanied with a detailed account of the reasons which led them to
take those decisions. The Holy See will examine each case carefully,
taking into account the links between the different local churches and
between each of them and the Universal Church, in order to promote the
common good and the edification of all, and that mutual good example
may increase faith and piety.
So, we can see that this would continue to be a liturgical abuse in any bishops' conferences where the two-thirds majority vote of the bishops was not obtained. Furthermore, since the Holy Father has not changed the existing norms, but permitted communion in the hand only by way of exception, communion on the tongue should never be denied.
As an addendum to this question, the document also outlines theological and practical reasons why reception on the tongue is superior to reception of the Eucharist in the hand:
This method of distributing holy communion [on the tongue] must be retained, taking
the present situation of the Church in the entire world into account,
not merely because it has many centuries of-tradition behind it, but
especially because it expresses the faithful's reverence for the
Eucharist. The custom does not detract in any way from the personal
dignity of those who approach this great sacrament: it is part of that
preparation that is needed for the most fruitful reception of the Body
of the Lord.
This reverence shows that it is not a sharing in "ordinary bread and
wine" that is involved, but in the Body and Blood of the Lord,
through which "The people of God share the benefits of the Paschal
Sacrifice, renew the New Covenant which God has made with man once for
all through the Blood of Christ, and in faith and hope foreshadow and
anticipate the eschatological banquet in the kingdom of the
Further, the practice which must be considered traditional ensures,
more effectively, that holy communion is distributed with the proper
respect, decorum and dignity. It removes the danger of profanation of
the sacred species, in which "in a unique way, Christ, God and man, is
present whole and entire, substantially and continually." Lastly,
it ensures that diligent carefulness about the fragments of
consecrated bread which the Church has always recommended: "What you
have allowed to drop, think of it as though you had lost one of your
