It's like going back a quarter century when all of the ISPs would only officially support Windows or Apple. I'd have to let them know exactly what information I needed (which if I remember right was pretty basic, like 2-3 items) and tell them to trust me to do the rest. Usually there was a little pushback because they wanted to go through their support scripts. I found when I started working in corporate jobs, I'd talk to the IT people and promise to do my own troubleshooting and I just about always was able to run Linux at work. Made for a much more enjoyable, and productive, work day.
