I use such plugins. Everything worked for about two weeks, and today suddenly this message appeared. As I understand it, you can’t hope that in the end all the plug-ins, up to one, will sooner or later turn out to be paid!?

I removed all plugins and the warning disappeared. It's strange that it didn't show up right away. It looks like a tricky trade trick :)
