The issue of software freedom is, not surprisingly, not mentioned in the mainstream coverage of Volkswagen's recent use of proprietary software to circumvent important regulations that exist for the public good. Given that Volkswagen is an upstream contributor to Linux, it's highly likely that Volkswagen vehicles have Linux in them.
Thus, we have a wonderful example of how much we sacrifice at the altar of “Linux adoption”. While I'm glad for some Free Software to appear in products rather than none, I also believe that, too often, our community happily accepts the idea that we should gratefully laud any company that includes even a tiny bit of Free Software in their product, and gives a little code back, even if most of what they do is proprietary software.
