I’m wondering what makes Purism’s case potentially part of the problem. Is it because they labeled it a “subscription” instead of “membership” or “recurring donation”? Is it because Purism is not a non-profit but a social purpose corporation (Announcement post [2017]: https://puri.sm/posts/purism-now-a-social-purpose-corporation/)?
The FSF, LibreOffice, Blender, GIMP, Inkscape, Krita, and many others ask for some sort of donation. System76 accepts donations for Pop!_OS (Click the “Support Pop” button).
If Purism does impose enshittification of their products, they aren’t locked down so we can use other software instead of PureOS and also hire people to work on alternatives (like what some other forum members have looked into, and this too).
