Python 3.0 was released almost 15 years ago and it was clear at that point that Python 2 would be shown the door eventually. My empathy for any complaints regarding that switch is exactly 0, even for open source projects.
I've had to deal with a lot of stupidity regarding Python, and that started with assuming that /usr/bin/python is Python 2. Why? Because that was the default in distros for just way too long, and some of the problems only got fixed after the distros went with Python 3 as the default. Obviously some people need to get the rug pulled under their feet before they start moving.
