Civilization will certainly not fall apart if language changes again, as it has for the entire history of spoken language - notably, Old English would be unintelligible to most of us now and civilization is working just fine. I just learned looking this up that Early English had a 4-form system consisting of yea/nae/yes/no ( https://en.wikipedia.org/wiki/Yes_and_no#The_Early_English_f... ), which is fascinating, and we appear to be doing just fine without yea and nae nowadays.
Anyway, I'll note that release and drop are near-synonyms if you're talking about a physical object, so their similar use for features etc isn't wild at all, and is well established in culture (drop an album, etc), so I don't think this is nearly as big a change (like yes->no would be) as you think.
