There is another product I use that has a freemium model. They hope to monetize a paid tier for users who use the product a lot.

In order to build trust, they open source their product. I forked it, removed the blocks from the freemium feature in 15 minutes using Claude Code. Never published the code to anyone else, just used it myself

Unfortunately, I think it isn’t going to be tenable for systems to be fully open sourced going forward.
