That's the point of Dirk S's line:
Don't look at the mountains in the distance. Focus on the concrete steps you can take now.
I don't just make this stuff up, you know. I've done it. I have worked in several different "100% Microsoft" companies in the last decade, and used Linux and FOSS to do it.
Either a Linux desktop and remote-desktop clients, or Windows with locally-installed LibreOffice etc.
The loud MS pundits say it can't be done, that the compatibility isn't there, that you can't round-trip.
The loud MS pundits, though, we must remember are the folks that are too technically incompetent to run Linux and too bigoted to run Macs. They're the scum floating at the top of IT. They don't know JACK from Pipewire, and they are wrong.
You can do it. I know because _I have done it._ For years at a time. The companies never even knew. It works fine. Even Thunderbird can now talk direct to Exchange without plugins.
You focus on the achievable stuff.
1. Add new local clients on existing OSes. Help users adapt.
2. Remove expensive proprietary client apps. Put 'em back for the 0.1% who need them and make it clear *all* costs are going on their budget.
3. Now you have more open client apps, add new standards-based server ones. Start turning off the paid ones and consolidating and downscaling.
4. In parallel you can start replacing some client OSes.
You do this aggressively and in 1 PC refresh cycle you've saved 25% or something of the license budget, Finance is on your side and likes you, and you've reduced your exposure to attack as well.
Placate the loud tech-nitwits in suits with shiny Macbooks.
End result: no change in strategy, no big bang, but you cut your outgoing costs, you cut licence fees, you cut malware vulnerability, and you're still in the same networks and partnerships and the others don't even know you shifted.
Don't move mountains. Dig up the paved-over garden and regreen it. Leave the mountains where they are. Worry about the yard.
