There are some fair points, but unlike C or other languages that have "old" versions, most of the newer versions are compatible with this old code (as in, if you have some C89 code, you can compile it in the newest C compiler. Same with Fortran). This isn't the case with Python 3 (there are breaking changes), and I think it's fair that the Python core developers who, besides Guido, probably work on this for free decide that it's time to end the older, non-compatible version and give ample time for developers to move their codebases, adding bug fixes and security fixes in the mean time until EOL is reached.
My biggest gripe with this project besides calling this Python is that it's seemingly ambiguous with its code compatibility. I don't mind ambiguity in programming languages, but generally the ambiguous cases are explicitly defined with cases to explain them, and I don't see anything of that nature here, only something that vaguely says that if there's something that works in both the Python 2.7 way will be the default. Without defining those it's hard to know what could happen in an edge case and this could introduce specific bugs that don't present themselves immediately but introduce data weirdness because the cases where something may be ambiguous wasn't defined.
In any case, I think that if a company has a really big, maintained code base in Python 2, it's their fault for supporting an older, in-2020-unsupported version of a programming language and the money/developer time spent supporting the codebase could be spent transitioning it to Python 3. I can understand a little more with an open source project because time is more precious and generally that time is donated, but even then most bigger projects (Numpy, Scipy, Django) have moved to Python 2/3 compatibility so unless the project is gargantuan there's no real excuse besides the project is not maintained.
They transitioned with a lot of community support and did sooner the course of years. It wasn't easy to support 2/3 out of the box. For a normal company, staying on 2 is like keeping technical debt and we all know how companies loathe to allow weeks for major refactoring when the gains aren't immediately visible. My company switched to using puppy and eschewing c extensions before we supported python 3.
