USA Today is presenting correct facts, but they're a bit outside of context, which has allowed you to jump to a conclusion that's actually quite wrong.
As Mikeazo pointed out, the Lord will not force anyone to be married to anyone. That would be unjust.
But you appear to believe that temple sealings are as disposable as civil marriages. They're not. You also appear to believe that a woman who marries after her husband has passed away is doing so because she wants to be married to two men for time and all eternity or because she doesn't want the first husband anymore, preferring the second. Those are false assumptions.
The rules of marriage in the LDS Church are based on Doctrine & Covenants 132—which also is the source of the Church's rules regarding plural marriage (popularly known as "polygamy"). Basically, the rules of marriage and polygamy allow a man to marry multiple women—but not a woman to marry multiple men.1 Therefore, it is permissible once a wife dies for her husband to marry and be sealed to another wife. But it makes no sense that a wife, when her first husband dies, be sealed to another husband when the second marriage is for companionship and not eternal exaltation.2
I hope you caught that last bit—not for eternal exaltation. Part of the problem here is that we're convoluting two ideas: obedience to the commandment of the Lord in D&C 132 to attain exaltation in the Kingdom of our Heavenly Father, and earthly marriage for companionship.
Therfore it's important that you understand the following: in the LDS Church men and women both have the same rights and privileges when it comes to terminating a temple sealing. Men do not have more rights than women in this regard.
But when it comes to maintaining the rights and privileges associated with a temple sealing, that maintenance is dictated by the commandment of the Lord in D&C 132, which permits men to be sealed to multiple women but not vice versa.
Please note that the value of Mikeazo's answer cannot be overstated, and I've upvoted it. The Lord will not force anyone to be married to anyone they don't want.
One more thing, and this isn't really part of your question but as the question touched on plural marriage it's worth saying as a follow-up detail. I said D&C 132 contains the basic rules for marriage in the LDS Church, but there is one exception. Official Declaration 1 discontinued the practice of cohabitation. Said more simply, men are no longer allowed to be simultaneously married3 to more than one woman. So while all the rules of plural marriage are in play, the factual reality of plural marriage does not exist. I've heard one man crow that he was plurally married because he had a civil divorce from his first wife, but not a sealing termination, and then subsequently was sealed to a second wife. On paper this looks like polygamy—but it's not. D&C 132 states that a temple sealing mus be confirmed by the Holy Spirit of Promise, and since we believe in sustaining the law (Article of Faith #12), where there's no civil marriage, there's no temple sealing no matter what the paperwork says. Chalk it up to the complexity of bureaucracy.
1 I say "basically" because it was not uncommon in early Church history for women to also be sealed to Joseph Smith or other prominent Church leaders. This was based on D&C 132:41. I don't recall if any such union was sexually intimate and I believe the practice ended before the 1880s. Anyway, this is why the Church's practice is referred to as "polygamy" and not just "polygyny."
2 Contrast that with this: a woman previously married civilly who either divorces or is widowed and subsequently marries a second man can be sealed the second man for time and all eternity. In fact, that woman can choose which man to be sealed to.
3 Married—not sealed—as in "sleeping together."
