Do you think Google and Bing are endorsing top results, and in particular endorsing a result like that in the specific context of what manufacturers I consider buying from?

That's the only way they would be disagreeing with me.

What torvalds is complaining about is absolutely true, but the problem is that most users do not give a shit about those issues. Torvalds disagreement wasn't about bugs in-, or complains about the quality of the proprietary driver, he complained about nvidias lack of open source contributions and bad behavior towards the kernel developer community. But users don't care if they run a proprietary driver as long as it works (and it does work fine for most people).

So you see now why that's not very relevant to end-users experiences they were talking about?

No.
