To be fair, I've caught autocorrect inserting apostrophes in my plurals more than once.

Apostrophes for plurals are sometimes the better choice, despite what style guides may say, for informal communication where acronyms are used and the lack of an ' may confuse people who think that the final lowercase s should be uppercase and part of the acronym.

As Orwell said, sometimes using some barbaric language construct is better than adhering to perfect style :-)
