I log in with my personal Microsoft account on one profile. I use a local account for a work profile that also has a MS365 account added to it (to avoid being joined to the domain). I have a second MS account for a side project. I have a second local account for a second job that uses Google Workspace.
I use Windows over Linux because it’s more convenient. Although that’s only because I’m forced into Office for work. I could probably switch to Linux for 80% of my stuff. I have a Linux install for development, but rebooting to do a quick task is a pain.
I think the government needs to break up big tech. The anti-consumer behavior they’re engaged in because they have no competition is crazy. IT costs for small businesses have skyrocketed in the last decade. Everything is a subscription and costs 3-10x what it used to.
