It's not one person. The maintainer's been getting abuse over their decision to rewrite the plugin for quite some time now, despite being very clear about what they're doing. It's fine for users to be upset, but not to treat the author like this.

What will happen now is not clasons problem anymore I guess.

The point they seem to be making is that it never was their problem, but they were just solving it for everyone for free anyway, and in return they were doing it wrong and they should stop interacting with people.

Honestly even when people are being paid to work for you and their job is to do what you ask them to, speaking to them like that is never going to work out.

I'm pretty sure this is not over a single user, but this was simply the straw that broke the camels back
