After using WSL for 6 years to do 99% of my work, our IT finally started to support Linux, so I re-imaged my notebook immediately. It's not perfect and we do have some mandatory security and backup solutions that slow things down a bit, but the good news is that they allow us to re-nice them, so it's not that big of a deal. The biggest challenge is Libre Office versus MS Office, because things don't always convert the formatting correctly, but it's still worth the hasle to avoid Windows PITA issues.
My home desktop has been on Linux for almost a decade, and a few months ago, my employer certified Linux as a choice for our corporate laptops. I couldn't be happier. If only I managed to convince my wife to take the plunge, but she is the most anti-change person I know when it comes to technology. It took her months to stop complaining when she had to upgrade to Win 10 and her 9 years old computer is slow as it gets right now, it was never re-installed and she rather not risk trying to make it better in fear of breaking something...
I've been trying to convince my wife to dump Windows for years, and her question is always the same, "will I still have MS Outlook? No? Then I don't want it". Her Windows 10 computer is 9 years old, has never been re-installed and it's slower than a freaking tired snail...
Then people will have a reason to change other than just for privacy concerns...
I'm guessing all the people suggesting to ditch WhatsApp have never been to Brazil. Everything there is done with it, you can buy groceries, medicine, do banking, get services, take out, etc... Getting the whole country to change will never happen. So, yes, while some of us do install Signal, none will ever uninstall WhatsApp...
I was an Arch user for 7 years and it never broke on me. Started with Gnome, than changed to XFCE after a couple of years and on my last year using it, I had no DE, only a WM. So multiple configurations, all rock solid. And I learned a ton in the process. Highly recommend using it.
