Sad to see this downvoted without any response, because as far as I see he's exactly right.
The only reason they dominate the PC market share is because their spyware OS is installed by default and people don't go around switching OSes.
An anecdote about security; at my workplace, one of the top 5 security firms in the world, secure boot isn't required nor is MS. Makes you wonder.
You might as well call other tech Linux doesn't play well with "vendor-locking" as this point with no concern, even if there are no real "locks" like that, just lack of support. "TME doesn't work? Literally vendor-locking and Microsoft propaganda!1!"
Security corporations, known for their cargo culting in addition to the usual corporate bullshit, aren't a great example. But bringing then up like they somehow were... makes you wonder indeed.
I fail to see in any way how preventing the loading of unsigned drivers in the secure boot chain is "vendor lock-in".
Furthermore, that signature does _not_ have to be Microsoft's. You can sign a driver with a private CA and provided that signer is in the trust store, it will be loaded.

Cool, my dad works for Nintendo tho. Agree with other poster, not sure if you even know what Secure Boot is. Seems like you read an article on Slashdot about it 10 years ago.
