100% agree and support your determination. Unfortunately, however, it's not gonna happen.
Currently, Microsoft (and other companies, but mainly Microsoft in Poland) offers schools and universities discounted Windows licenses, as well as very cheap or straight up free Microsoft 365 packages for all students. It comes with 24/7 technical support, which education facilities desperately need, since staff is tech illiterate and they can't (or can, but won't) afford IT departments.
Furthermore, Poland is an American puppet state, and won't make any decision that substantially hampers American interests. As we've been shown many times over, even in just the last two years.
It's so obvious that children and students, especially university students in tech fields, should work mostly with FOSS, unless a FOSS option is unavailable (very rare cases). Not only would they get more meaningful knowledge and skills, but the country would reduce its dependence on the US Empire as well. If only governments ever did the obvious good thing.
