I agree. I’ve probably spent a little longer thinking about “ownership” issues around open source as a result of having once ('99-'00) worked for a company that was selling a dual license open source product to enterprise customers. An unusual situation that in hindsight isn’t entirely in the spirit of open source, in my honest opinion.
But I also wonder about certain efforts around open source projects with my current employer. Sometimes companies will take an open source project, slap a very thin UI on top of it, and some authentication and payment mechanism, and then rent it out as a SaaS. In effect, the company has taken some “ownership” of the thing. It’s odd.
