I've been around the block on this sort of thing for a while now, on various other entertainment-media subjects. I know what this is. This is a combo of trend-chasers trying to be trend-setters, and people reading tea leaves way ahead of any actual....developments.
So, you know me. You know I'm not going to give 5e a pass if I don't think it's (very) well-deserved. I don't think D&D 5e is dead. Instead, I think folks are correctly seeing the waning enthusiasm. I think folks are catching on to the very very very first blush, the first tiny inklings, that the proverbial "spark" isn't there anymore. Doesn't mean folks aren't having fun, lots still are, of that I have no doubt. Doesn't even mean the game isn't growing, it probably still is! But we have passed an inflection point.
The instant it looks like things are going Not So Well, the social media feeding frenzy begins, because being THE VERY FIRST to report on some controversial thing nets a creator money and attention.
Maybe--maybe--in another 2-3 years, we'll be seeing this in a much more serious and meaningful way. For now, just view this like tabloid magazines pontificating about allegedly-explosive exclusive reveals...90%+ of which are at best the result of someone casting molehills to mountains, and at worst outright intentional and knowing bovine feces. For the time being? Just means we're hitting the natural and expected slowing-down period after an edition has passed its peak. Which...should not be a surprise to anyone given we now have 5.5e and it is being openly called 5.5e now.
