I went 'no' to 4e, didn't bother with 5e, and didn't bother with Pathfinder 2e.
I have enough d20/3.0/3.5 stuff that I have never used in game that I've never been concerned about adding new content.
I own all the Paizo adventure paths up to the end of PF1E, and have only played through three of them so far.
I have entire campaign worlds I've never even touched.
So this doesn't really effect me.
My advice for everyone - if WOTC is taking a naughty word on the industry, just get all their pre5e stuff, and get all the OGL stuff you can, and just enjoy that until the end of your natural life. There is more then enough out there already.
