When you’re accustomed to privilege, equality feels like oppression.
Instead of demanding why we’re “forbidding” you to run Python 3.11 on Windows 7, why not instead ask: Why are you demanding that the Python core devs test every new version of Python on all the old versions of Windows? Remember, you’re here asking about Win 7, but someone else will be asking about Win 8, another person will want XP, and there’s probably someone still running 98SE out there. Is it reasonable to demand that the Python developers test their code on all of those versions?
Remember that supporting old Windowses is work and someone has to do that work. Supporting current Windows is work too, but it’s work that benefits a lot more people.
Download the source code for Python. Download a C compiler. Build it yourself. Or find someone who’s willing to do that for you, possibly for $50/hour or more.
Insulting people is not a good way to get them to do things for you.
