Normally you ask for payment upfront, not years after.

Who got asked to pay years after...? After what?

Best read: You are confusing different products. Somebody can do two things and get paid for only one of them.

Worst read: You are really trying to confuse them.

Nobody is asked for money years after they started using Tailwind. Nobody is being asked for money now, when they start using Tailwind.

So fork and offer your better free version. Holy fuck. What's with this persistent attitude that open source creators should slave away for free forever?

Either you support an economy where everyone gets a meager living wage just for existing and then once that's established you can complain about people trying to make money off open source, or you say "capitalism as it exists is great" and swallow the fact that people who you don't pay don't work for you. Which is it?

Once you give it for free, you must work for free forever!

Please, just admit you're wrong. It's ok.
