Hello, lead dev here. Yes there's ugly personal history, but as I said, I don't want to get into a he said/he said discussion because it won't go anywhere. Will just say that it's bad enough that it forced us to rewrite an AGPL library (in which I was personally contributing for months) from scratch instead of reusing it, as we had all the permission to do so. That's how bad it got in the background.
That said, I was under the impression that my actions were License compliant due to section 7b

I.e. since that blurb didn't request explicit preservation, it was ok to remove.
