I rather they lock it down tbh
Yup, they would be better of taking ownership of their tech and probably going closed source way now assuming they are serious about getting their tech into games.... but given that what only 2-3 consoles games STILL only have FSR, this kind of says it all tbh...... Also, read their official github page of the open/closed issues for the repo where you see developers asking questions on issues with fsr regarding how to update the fsr version yourself (same way rtx owners can do with dlss). Essentially, you can't because of the way amd have created FSR, they have done it in such a way so it's entirely up to the developers how it gets implemented and compiled, which is a good thing in its own right i.e. more choice for developers to choose what works best for them and not be restricted to one way dictated by said vendor but like I have always said before based on my own experience, this is also a big con especially if the vendor i.e. amd don't provide any support/guidance to assist.
I think I am justified. The question is were Nvidia lying about it not being possible to make frame generation work well on Ampere and older.
This has already been answered, ada has a significantly more powerful optical flow accelerator that makes it possible for ada to provide a good experience in terms of low latency increase as well as IQ iirc, so the reason they haven't enabled it is they don't want to get "crap reports/posts of how it sucks on anything but ada" which is probably a good thing (assuming that is true) as can you imagine how many articles and posts there would be here slamming how poor dlss 3/FG is.....
It'll be interesting to see amds version though as supposedly nvidia have been working on theirs for 6 years (even before dlss came along) especially around lag. I'm not expecting good results outside of their 2-3 PR/sponsored games especially considering how far behind they are in the upscaling department but who knows, they could knock it out of the park here....
