For at least the first four or five years of 5e's existence, it was genuinely impossible to voice criticism thereof.
I had people say, to my (internet) face, that it wasn't possible for someone to not actually like 5e, because it had something for everyone. That nobody could truly dislike it. Any criticism, no matter how mild, would in fact get drowned out by folks only interested in singing its praises. Even the few "criticisms" were often, if you'll allow the turn of phrase, praising with faint damnation.
I am, to my surprise, seeing very little of that here. Perhaps, with nearly a decade under its belt, it's finally possible to criticize and not have seven people jump on you for disliking something. I'm quite surprised, for example, to see people generally agreeing that 5e lacks for options. Even as recent as a couple years ago, accusing 5e of lacking options was controversial, e.g. several discussions of Level Up getting crowded by posts talking about how that isn't necessary, or threads about what's missing from 5e being taken over by claims that it actually has too much already kthx.
