Most of those things seem to be true. The 3dprinting mod did endorse those 2 alternatives, and they seem to be the mod of one of them, they also seem to be doing a terrible job moderating the instance they created, and the users of r/3dprinting seem to be spamming it because they disagree with how the mod handled things, and I'm guessing the mod didn't get buy-in from the users of the sub before trying to migrate. I don't think that necessarily makes sub.rehab dodgy, they are accurately communicating alternatives both mod-endorsed and not.
