As an end-user, I do. Being prevented from fixing my own (expensive) device is not something I would voluntarily subject myself to. For context, here's a comment I posted a while ago (https://news.ycombinator.com/item?id=13527205):

I used to be a big fan of permissive licenses until I bought a $700+ android phone a couple of years back and discovered that it did not "support" my native language (it could render the glyphs but system-wide support was not enabled).

Having extensive experience with unicode and how text is usually rendered, I knew exactly how to fix the issue; the fix was likely as simple as injecting an SO that hijacks a specific system library function. However, because the phone was locked down, I was unable to fix the problem myself. All important system apps including SMS and the browser displayed gibberish.

It was the most expensive brick I ever bought. This experience taught me the true value of the GPL and why user freedom far outweighs the freedom of developers
