I doubt it and that argument makes no sense. Copyright is extended thanks to the lobbying effort of huge business like Disney in order to make a ton more money.

Unless you see some big corporate support contracts coming over the horizon for PSF, not to mention they'd have to be worth the money vs the technical debt, I don't think Py2 support will get extended.

Backlash from the tons of big companies still using it will become lobbying to keep it supported. I don't expect them to stop in the next couple years, or the next few, etc.

There's less muscle behind keeping Python 2, but there's a lot less muscle needed to keep it going than to extend copyright.
