Also an important aspect for companies is liability. If the app they paid money for screws up customer data they have someone on the hook for that. If the FOSS version does the most they have on the hook is the 40 year old dude living in his parent’s basement maintaining the project they used. Not much money to be got there for damages.

I agree, though I think LibreOffice is not a great example as there’s very little room for error and something that you would need “dedicated support” for. That’s how I see it anyway. Never worked in an office.

However, the majority of companies that require using paid proprietary software also require the use of Windows itself. A safe bet in this situation would be to just set up a VM for work and use Linux for everything else.
