The problem with VC-founded projects is that there's some kind of rug-pull, ads, privacy violation (e.g. using repos to train AI) or "feature enhancing" subscription likely coming.
As a user who would need to invest time and effort in using Tangled, I think it's fair to ask to have the plan explained. I'd rather see explicit price for services than see enshittification happen.
Just like engineering, monetizing is an iterative process. As long as they don't make it hard to move off their platform, IMO it's completely fine for them to try different monetization models.
We should celebrate people building open source stuff and in the public. The alternative is for the software tooling ecosystem to look like EE or mechanical engineering tools - all closed source, proprietary, and with super expensive licensing.
It's easy to take open source for granted - 'information wants to be free', but we are at risk of the open source movement dying with proprietary AI completely changing everything about software.
If we penalize people who are working toward the right goal, we contribute to that decline.
