> Again, please show me any talk which says, that developers benefit from the need to address vendor lock-in

I don't believe it is a benefit for game developers. pjmlp already hinted some points. I will describe it a little differently.

For OSS hackers it is very important to be able to debug the things on their own. Game developers probably simply don't have the time for this. They instead buy support from the hardware vendor (AMD, NVidia, Microsoft, Sony, Nintendo etc.) if they get into driver bugs that they can't trace down on their own. Even more: In many PC game development studios there sit programmers that are actually financed by NVidia ("NVidia mafia") whose job is to make the game run fast/good-looking on NVidia GPUs (and perhaps worse on AMD ones ;-) ). In particular gamers playing on AMD GPUs are of course critical of this fact for obvious reasons. Now I ask snakily: What service do OSS (including OSS GPU driver) developers offer/deliver to game development studios to make the game-in-production run well on GNU/Linux and/or on open source GPU drivers? This should perhaps answer your question why game developers often don't care about OSS drivers etc.
