Thats not actually the point of OSS. And RMS is not god and does not define it
The point of OSS is to not get fucked by the vendor. The point is not getting locked out of your shit because the vendor was taken over by some shitbag company like Broadcom and completely changes the rules and then holds your existing use of it hostage because they can. Or refuses to spend their time dealing with your scenario for your business. Or a thousand other reasons that have 0 to do with paying for it.
GPL nutjobs have this silly fantasy about never paying for it, but they have corrupted the actual meaning for that purpose, not what was intended.
The GPL virus has always been problematic for business, which is why the smart ones use MIT/Apache/BSD software in their products and why ACTUAL OPEN SOURCE advocates dont use GPL for their stuff, its more restrictive than pretty much any source license Ive ever seen.
Open source means the source is available for you to use under clear guidelines that apply to EVERYONE equally ... transfer of money for it has exactly dick to do with it.
GPL is just a fetish for those who refuse to understand how the real world works. Which is why no one can name a successful company that ONLY uses GPL software. Every one you want to name sells proprietary software to make money while piggy backing on GPL software. I challenge you to name one that doesnt.
Yes, Linus and Linux are successful ... but you notice they didn't follow that nutjob shit in GPL 3?
If you want Open, GPL ain't it, its restrictive as shit. Microsoft has licenses that arent nearly as restrictive... for a fee. Microsoft will hand you the windows source code - for a fee, under terms that meet the OSS definition but not in a way that let's you sell/steal/copy theft it.
GPL itself isnt evil, its goals are honorable. But 99.9999% of GPL nutjobs only like it cause they can use it without compensation. For them it has nothing to do with 'open' and everything to do with being cheap assholes who dont think people should be compensated for their work. They cant use it themselves, someone else has to make the binaries they goon over, or build system for them.
GPL is almost always used as a weapon.
