I’m sure that’s correct. Richard Stallman would be a good example of that, sadly. I doubt anything as negative has been said in this thread, or site. Seems more like people feel attacked when free software advocates point out uncomfortable issues. Like how people get annoyed with vegans talking about animal cruelty (I eat meat, saying that to avoid theonejoke).
If one limits their scope to the nutrients or taste of food on their plate then they wouldn’t consider the well-being of other conscious creatures. Only considering system requirements to complete an activity misses out the freedom of the user(s), apparently.
It is a given that humans suffer due to the unjust power that proprietary software gives devs over their user’s computing. Even the best dev does not the the willpower to always resist the temptation to use that power at the expense of the users. Many devs are oblivious they are doing anything wrong and many are malicious/anti-consumer.
There is also the impact it’s use and promotion has on others - money/feedback/promotion given to the non-free projects are boons not given to the freedom-respecting projects. I am better off when others start to move away from proprietary software.
