The title of this post is misleading. If you follow the links, the dev says they are releasing a $3/mo subscription service for their app starting on 08/30.
The current Infinity app will stop working, and you have to install the new Infinity app, which is the same but with subscription.

Isn't this a separate package not part of the Linux kernel? I don't see why Linus would have to get involved.
