Linux is generally not happy about seeing any out of tree drivers.

But that is also not without reason, in a certain way Linux balances in a field where they are and want to stay open source. But a lot of users (and someteimes the companies paying some "contributors", too) are companies which are not always that happy about open source. So if it's easy to not put drivers under permissive licenses and still get a good experience out of it they will have very little sensitive to ever make any in-tree GBL drivers and Linux would run at risk of becoming a skeleton you can't use without accepting/buying drivers from multiple 3rd parties.

Through take that argument with a (large) grain of salt, there are counter arguments for it, too. E.g. the LLVM project with is much more permissive and still maintained well, but then is also a very different kind of software.
