It's a Dilemma Foss vs. Profit.
I tried running FOSS for my website, and well, it failed, quickly realized (too late unfortunately, for now) that if you want to offer people something you need to implement a business model as a redundancy just in case people aren't feeling generous.
And unfortunately it's why subscription models are the most popular model in software today 🙃.
People aren't generous because if they were we'd all be communists right now 😂.
