This is why I don't bother with AGPL released by a company (use or contribute).
Choosing AGPL with contributors giving up rights is a huge red flag for "hey, we are going to rug pull".
Just AGPL by companies without even allowing contributor rights is saying, "hey, we are going to attempt to squeeze profit out and don't want competition on our SaaS offering."
I wish companies would stop trying to get free code out of the open source community. There have been so many rug pulls it should be expected now.
