For my own part, I was one of the lifelong D&D players that left during 4E (I swear we gave it a chance) and moved to Pathfinder 1E. I did not engage in the Next playtest and honestly did not expect 5E to be worthwhile, but was pleasantly surprised. For years, i enjoyed running it and I agree that part of that was that in some ways it felt very much like AD&D 2E.
I was already getting tired of it to some degree before the OGL debacle, but that was the thing that broke 5E for me. I refused to give WotC any more of my money and did not want to support them by running 5E at cons, so I tried Pathfinder 2E (it turned out to be too fiddly for me) and ran lots of Savage Worlds and other games. What really put the nail in the coffin for me and 5E, though, was Shadowdark: I was presented with the fact that all the things I love about D&D I can do with a MUCH slimmer ruleset.
I don't expect to run 5E again. I certainly won't buy 2024 5E unless WotC makes good (for me, that means putting the 3.0 and 3.5 SRDs out in CC) and have balked a couple times now on buying ToV. That I actually put it in my cart yesterday whn it was stupid cheap and did not pull the trigger tells me I am over 5E.
For the record, I don't think 5E is a bad game, just that I am done with it. 10 years is a long run for an RPG. I would certainly at least entertain the idea of a 6th Edition (though issues with giving WotC money remain).
