Black defaults to 88 characters per line, which happens to be 10% over 80. This number was found to produce significantly shorter files than sticking with 80 (the most popular), or even 79 (used by the standard library). https://black.readthedocs.io/en/stable/the_black_code_style.html

I wonder why they don't reduce the indent size too if minimizing rows is of such importance.

The line width does make perfect sense if Black is the new de facto standard. I don't think it's the path of least resistance though. If 88 is used it will trigger other code style analyzers (it did for me) because they default to 79. PEP8 has been around for 19 years, black has a lot of work trying to persuade 19 years of people recommending following PEP8.

Have you updated the pep8speaks bot with this line length?
