They were willing to make some change to the major icky things, but didn't want to have to incur lawyer's fees to do so. (I was willing to take on 50% of the fee.) They said they had over 100 other people sign without issue.
I wonder whether or not I made mountains out of molehills. My lawyer, Mr. Miche and I all feel safer with me not signing. I don't think they were paying me enough anyway. I didn't stand to make a ton of cash from them overall, either.
Still ... icky.
