I mean in this specific case we're not talking about AWS or any other large company. We're talking about someone wanting to offer Bear.app hosting in the vein of managed Wordpress. This is good for Open Source. Having multiple commercial entities working off of and invested in the same codebase is exactly what Open Source envisions.

It does take some mental discipline to actually believe in the movement and not view someone using your software to start a business as them "stealing your work." Such a thing doesn't make sense in OSS, you gave it away freely. It's a good thing, the competition is healthy. You don't have to believe, closed-source proprietary software is much easier to run a business off of as evidenced by most businesses operating that way. There's no shame in it. The FOSS folks are the free love "we don't believe in intellectual property mann" hippies of the software world.
