The problem we have were I work is that there is no company our company can buy the product to. Don’t lough, we have a very hard time to convince them that we can support the thing for this reason. We are a team dedicated to the Linux support in the company though, so we have that at least.
The biggest difficulty to use Linux in a company is how the company usually work: they have a centralised database to manage user accounts and they usually use proprietary softwares for about everything : office, windows authentification and file servers, mails, etc. And they make it hard to use their stuff with free software. Teams for example barely works on chrome, and straight up doesn’t on Firefox. You also need to setup your infrastructure for security and stupid vpn software the sales got sold on.
Economically I’m pretty sure it’s still worth it, because our team is smaller than the windows team and everything is made for the windows infrastructure that we must plug into.
Oh and try to have almost any user use something else than office shit for desktop work, good luck for that. This is the biggest barrier for Linux use right now.
