It seems like most FOSS I’ve seen is a free, buggy, alternative to mainstream software, which resolves a problem the user had.
I don’t know what kind of sw you use, but usually I find Foss software to be sleek, functional, fast with good support and updates, while commercial software is ridden with ads, trackers, bloat and bugs. Exceptions on both sides but the notion that free software is generally worse is categorically incorrect.
Everyone can contribute, but how do they make a living?
So first not everyone can contribute. Usually people who also use the software and have personal (or monetary) interest in it, contribute.
And why does everything has to be about monetisation? Yes, both people and gigantic corporations make money off foss in various ways, I’m sure others have explained that already. But people also do things for other reasons than just money.
But I’m just baffled how people so often declare that foss can’t work or that it’s qualitatively worse, even though the entire planet has been dependent on foss for decades.
No, just because someone sells something directly, doesn’t mean it’s inherently better.
I use Session Messenger, on the Oxen network. Love it on principle even tho the implementation is a bit lacking in places.
And there’s Tor… Which is what it is.
