I'm not disagreeing with that.
However, a lot of these comments are made as supporting points in threads focused on adjacent topics, and thus they often lack specificity.
I feel like before the 3rd party apps go away, we have an opportunity to learn some things about UX.
- What, specifically, is bad about reddit's offerings?
- What design choices are common among 3rd party apps but which differ from reddit's?
- What innovations have 3rd party apps made that were picked up by other 3rd party apps and/or reddit?
- What design considerations are under-appreciated?
Those sorts of questions.
