enforced by who?
God?
you haven't thought this through
open source is a great way for corps to get free testers on one side but on teh other side that's how science works too
just cos you have teh code doesn't mean you know how to deploy it or how to attract users to bring in the money, and plus... that's the whole thing about bitcoin and lightning, it is a mechanism for that, which didn't exist before and as such we were saddled with the advertising monetisation model and shitty subscriptions and... lastly
how do you expect people to be able to trust to run your code if you only provide it in binary format or something? like, come on, think about it, the whole closed source, proprietary copyright thing is a fraud from the get go but it's not just a fraud it's something that is just begging to be broken
how long does it take for any given closed source software to be cracked so anyone can run it without programmatically enforced limits?
about 5 days i bet
there's guys who have been doing this for literally 30-40 years and they aren't gonna quit because that's their sport, by day they write embedded software
