FOSS is destroyed the moment that is introduced to the mix. Its like political sells - begin pushing a small degree, they wont notice the temperature as it rises over time until its closed source and corporate.
This is how you kill off FOSS, or your project. "corporate creep" I call it.
The software is still open and free.
But in your scenario you're just super angry you didn't figure out to make money off your work.
I'm gonna go out on a limb and suggest that you never, ever contribute to FOSS and instead just buckle down and focus on selling your blobs.
Note: I'm not saying you're an entitled consumer, but I interviewed many maintainers of successful Open Source projects. The number one issue for all of them was entitled consumers.
but what I see causing far more problems in the OSS community is greedy patreon gatewallers who poach all they can from the devs, then put it behind a patreon wall and charge money for it. Them and corporate swooping in are a bigger problem than whining on a github issues board.
And, yes, you are very correct that finding balance is very challenging. However, I feel that the OSMF suits the bill quite well, at least for projects of a shape and size that I'm familiar with.
