Well that’s a lie. Lots of companies use Linux servers, Linux embedded devices
I mentioned that
even Linux desktops for programmers or engineers. Android devices are everywhere too. One of the most common uses of Linux is smartphones.
They make money because they’re proprietary, sell peoples info, and because of that they represent everything the free software movement fights against. I use Linux because it supports the free software movement, not the other way around.
The better question is why aren’t people supporting desktop Linux?
It’s a combination of a few factors, developers are pressured into not asking for donations (users need to actively find their website to donate), the vast majority of Linux software is free of price, and people don’t want to pay money for their operating system.
