I’m not even claiming that people who feel thar feel that a social contract has been violated are correct.

I’m saying that the open source rug pull is at this point a known business tactic that is essentially a psychological dark pattern used to exploit.

These companies know they’ll get more traction and sales if they have “open source” on their marketing material. They don’t/never actually intend to be open source long term. They expect to go closed source/source available business lines as soon as they’ve locked enough people into the ecosystem.

Open source maintainers/organizations like the GNU project are happy and enthusiastic about delivering their projects to “freeloaders.” They have a sincere belief that having source code freedom is beneficial to all involved. Even corporate project sponsors share this belief: Meta is happy to give away React because they know that ultimately makes their own products better and more competitive.
