Henrique should take it up to his university. When I was a student, mine used to provide me with an account that could use desktop apps on Windows and Mac. Educational institutions get very cheap license bundles compared to enterprises btw.
(Also funny that he says we should not use proprietary software, but ignores his own usage of macOS.)
In this context they don't. There is no license where one can use PowerPoint on Windows, but not on macOS. It would not work on Windows either, because the problem is that his account is only entitled to the web version of the Office apps. The exact wording of the message he got is platform-specific and it doesn't even mention Windows at all.
