I agree with your re-licensing analogy, with one caveat, which is that the existence of a rug-pull project might encourage people who would otherwise contribute to more firm-footed, community-driven projects to essentially waste their time on a dead-end project that won’t last. Since every time a project dies, there’s wasted effort that could have gone into building something long-lasting, I think our collective time is limited and we should be building up projects that last so that we can move onto freeing up other bits of the stack.

That said, I recognise this is a relatively weak argument, because there’s so much duplication of effort anyway - everyone wants something slightly different so there are many duplicated projects, there’s benefit to exploring all sorts of different avenues even if they don’t work out, and ultimately this is a hobby and people have to work on whatever they want.

I also agree that a license assignment CLA is not necessarily indicative of a rug pull by itself (although it can warrant further investigation, and there is a pattern of people using it in this negative way, against the wishes of the community). I guess it comes down to people’s intentions and trust at the end of the day. A project I work on recently also switched license. For us it was permissive to GPL - there was no requirement for them to ask permission - but they still did check with everyone with more than a couple of lines of contributions because it was important for them to get consent. I know SFC for instance lets you assign your copyright to them to help with enforcement, but in a revocable way, so if you don’t like what they’re doing, you can always take it back.

I think to some degree I’m quite jaded and cynical, because I’ve seen this happen so many times, especially with more glossy and centrally driven projects. I’m drawn to free software because I don’t like abuse of power and to me this is a solution to that in the tech world. So whenever I see a power imbalance here, I react strongly against it even if in some circumstances it wouldn’t be abused.
