Aside: this is one of the biggest lessons of my adult life. Just because I could make something doesn't mean I should make something. Learning to value your time is a very underdeveloped skill.
If it is a sarcasm, then please mind that original comment author got really humped by this app's vendor when it stopped working. Maybe Stallman got something right after all?
In Stallman thinking though, he doesn't have the freedom to fix or update it himself.
(I don't think Stallman's ideas are necessarily right for everybody, but I'm glad he's doing his thing right out in his end of the bell curve to counteract the opposite end of the software philosophy craziness...)
Under Stallmans model the developer works for free, and I guess they need a second job to pay the rent. Ah but GPL doesn’t mean free as in beer? Oh yes for practical purposes it does mean exactly that. Outlier business models excepted of course!
Actually no. Under Stallman's model it is perfectly okay to demand and earn payment for your work, but results still would be free, quote, as in "free speech", not "free beer", unquote. Did you see bounty offers in open source repos' issues?
