But Linux is GPL! And Linus himself believes Linux wouldn't have become what it is now if it weren't for GPL.
In the context of Linus values, open source means basically the right of forking software, but copyleft means the right of merging back worthwhile patches from downstream forks. This is absolutely critical in an industry full of binary blobs: this is basically the reason we have any kind of source code for Android kernel drivers, routers, and many other products.
What Linus doesn't value is the goals of free software movement: empowering the user of the computer. He just wants the code. That's why he doesn't care about tivoization, but he cares a lot about GPL.
