The toxicity is not about accepting contributions. I have zero issues with this, the project is, as you said, his personal garden. But the behavior in chats is absolutely toxic.
If you put out a sign "come listen to my music" and then throw out every second person, everyone wearing blue and every blonde with no warning, that is toxic. It is your play, but you are not treating people coming in with respect. My 2c.
