I think it's more that they are just people doing jobs, and what we see as sacred safety nets/constitutional protections they over time just see as limits to doing their job so they work around them. Sadly it's not super nefarious, just human nature. I mean these lawyers upset now knew it was being done previously, but again, only so much they can do in their job and they let it slide too. They were also part of the slippery slope. Again because ultimately they too are just doing a job. Human systems that defer to people (in the court given 'good faith') will get abused up to and just as far past the line as they can get away with. And once normalized the lines move further back.
