One software freedom that Stallman does not mention is the freedom *not* to use the program because you dislike or don't want it for some reason
Free software tends to be flexible, have clear boundaries, split responsibilities, and replaceable components, thanks in part to openly defined protocols and formats
Proprietary software tends to want to lock you in into their freaking ecosystem, and even if they adopt an open standard, it's a part of an E-E-E strategy
Got asked to fix old, virus infected PC. This is how it looks
I'll probably start by checking what people I follow use.
I value personal freedoms and respectful discussion of issues.
