It's so predictable that people would run with conspiracy theories that make no sense and link to things that are completely unrelated. The "issue" that came up today in this article has absolutely nothing to do with SecureBoot.
Microsoft has already used SecureBoot to lock out Linux 'offer better security' on their phones and tablets. Is it really such a stretch for people to be afraid that they're going to require desktop/laptop vendors to leave SecureBoot on in the future? (and conveniently only recognize the key for Windows?) Probably our best saving grace against that is how rapidly mobile is cannibalizing the desktop/laptop market. Pro…
The PC market and mobile phone markets are very different, with a huge precedent already being set that mobile ARM devices are locked down. Are you equally upset that iPhones and virtually all Android devices also have locked down bootloaders?
On top of this, Microsoft cross signs the keys used to sign the Linux bootloaders so that they work out of the box even on computers that have only the default MS keys enrolled.
Considering that most people fail to grasp those two salient points when presenting their conspiracy theories... yes... I feel comfortable dismissing most of them out of hand.
