I've been using Microsoft Office for decades, and it is and always has been a generally excellent product. That's much more than can be said about Windows.
Using a Microsoft product like this has however always made me uncomfortable, and there is a steady drumbeat of news indicating that it may finally be time to bail.
I have no interest in training anyone else's artificial intelligence models for free, and especially not those of an anti-user criminal enterprise such as Microsoft let alone an openly anti-human organization like OpenAI.
There are other reasons to jump ship as well. I resist tapeworm software models (better known as subscriptions) as much as I am able, and to this day I've evaded Microsoft Office's criminal "365" platform. I rely on the gray market to obtain legal license keys for Office, and this has served me well for the past decade.
Something has changed lately. Gray market keys for Office 2024 cost ten times what keys for 2021 did, and none of these versions have Microsoft Access (which I use). Likewise, despite being out now for more than a month I've yet to see a Windows 11 Enterprise LTSC license key on the gray market. LTSC versions of Windows are essential ever since the release of Windows 10 in order to evade Microsoft's constant assaults on users.
2025 may be the year that I not only shift to LibreOffice but Linux as well.
