If Microsoft could make me move to Linux, they will be getting a lot more people to switch. I was very into Microsoft's OS since v3.0, I used Outlook for all my email for decades. I recently moved over to Linux Mint and Firebird for email and have not looked back. All my Windows VMs are now Linux VMs. All of Microsoft's invasive "AI" was the last straw. I don't like the direction they are headed.
I was a bit puzzled by Firebird (I thought that’s a fork of Thunderbird, like, say, LibreWolf or Waterfox), but I couldn’t quickly find the project, so my assumption is that it’s just the misprint, and author thinking of Fire-fox -> Fire-bird, not being into ecosystem for too long to remember the actual bird. Anyway, that’s irrelevant to the point author’s making, and I’m happy there’s a new Linux adopter now. Thanks, M$, I guess.
