Well, I think some companies had a massive conversion burden, but these are typically massive companies, like Google. Most companies had nowhere near as much python2 code. I think you hit the nail on the head with "lack of meaningful tests". The entirety of "locked to 2" python code I've dealt with was a serpentine mess with little/no tests and so brittle even going from print to logger risked things breaking. "But it currently works!"
