On the contrary, I would say this is increasingly unusual nowadays. There are print restrictions on e.g. iStock content, but there's no attempt to "ration" the number of visitors that see a stock photo at a specific price point.

It's something that's generally put me off from licensing paid fonts - despite the work that has gone into them, because you're almost signing a blank cheque and it's not easy to know how many visitors are scraping content for LLMs.

Inkscape lets me adjust kern of each letter because the curve can cause letters to touch.
