Not hating on open source, just let people use what fits their expectations and needs and stop deterring them with gatekeeping :P
UX = user experience
My point about still being able to charge stands. I've seen OSS do it - if you want it quick and convenient you pay e.g. through Google Play store or official website. Yes cheapskates will compile it themselves or fork it or grab a free version from F-droid etc but they were probably going to pirate it if it was closed software anyway.
