I was a user of several microsoft services that worked relatively well. On computer I used to have onenote and onedrive. On phone I also had the outlook app to manage all emails.

For exactly the very same reason you stated, I have stopped using them. Whilst I can still use them on my android phone, there is no point if they dont sync to my computer, and they don't sync to my computer because I am afraid of putting my microsoft password in anything that is not firefox.

Hence, I already moved out from onenote to Joplin (still synced via onedrive), (I am not happy with the move) and I stopped syncing with Onedrive, and will have to move soon to something else. On my phone I stopped having outlook, and I am back to use each app for each email.

As you, I am also trap on windows (tried fedora, it simply didn't work).

Sad times for people who want just a computer that works.
