Yes. I have actually done phone support, and you would not believe how dumb some people are. Many will call for support before they even turn their computer on. They want someone to babysit them through the entire process before they even try to do it themselves.
Come on, those kinds of people don't run Linux at all. The Linux problem is pretty much the exact opposite, you've got a bunch of dangerously knowledgeable users who've all tweaked their setup and expect all their special little snowflakes to be supported even though it's not.
I got someone a few weeks ago running Linux who didn't even know what distro they had. Their brother had set the machine up for them.
We figured out they were using Ubuntu. This is an Internet tech support outfit and I was the second person to talk to them. We found the networking on the machine was disabled. Re-enabling restored the connection.
Sub says they had tried that with the last person they'd talked to before me a couple days ago, and it would just go back to being disabled after it tried enabling for a few seconds. The issue they were having had magically resolved itself.
I have my mom running Linux now, too. She would be smart enough to know it's Linux Mint, but she wouldn't be able to do much else.
Linux is gaining usage from people with older hardware that was running XP before support ended who don't want to or can't afford to upgrade. These people are generally not computer savvy, and a platform that is more secure and less virus-prone than Windows is a good fit if they spend the vast majority of their computing time on a web browser.
