Pytorch and tensorflow are from FANG. Without OSS being a thing, they just keep using it without sharing it to the world.
Your examples are actually proving the opposite of your point :)
But OSS is a thing and they did share it with the world.

How so?
Despite the fact that Big Tech doesn't need OSS, it's not true that BigTech:
1. "doesn't use OSS", or
2. "has internal versions" [of any relevant OSS], or
3. "only use it for recruiting".
Hack isn't a counter-example; it's open source. The face that TensorFlow started a google isn't relevant to my point, nor is the fact that FB took the healm of Torch from academia a while ago.
Companies engage with OSS strategically, not altruistically. In other news, grass is green :) But there are many strategic reasons for having pieces of infra that are (1) OSS, (2) not duplicated internally, and (3) have motivations other than recruiting.
Although even if all OSS software that we've discussed here disappeared tomorrow, I know at least Google and Facebook are fine because they don't use any of it. They have their own internal versions that are better and aren't shared with the world.
