It's all business.
Slightly off topic... I've not read the terms or anything, but I have a few open source plugins on .org, yet their commercial domain (which shows the same plugin) has this exact terminology in their plugin directory:
Sorry, what? My open source plugin is free if someone subscribes to their product? And sometimes their commercial domain comes up first before .org (which was a whole uproar with developers in 2023). Our hands are unfortunately tied.
At the end of the day, it's all about corporate entities and how they market to the end-user. Screw the nice guys!
