It’s not even that.

By and large, most industry standard softwares are only available on Windows and macOS. Take word processing for example. It doesn’t matter if there are open source alternatives that gets it 95% of the way there. Companies by and large would not want to run the risk of that last 5% (1%, 0.01% doesn’t matter) creating a situation where there’s misunderstanding with another business entity. Companies will by and large continue to purchase and expect their employees to use these standard softwares. People will by and large continue to train themselves to use these softwares so they have employable skills so they can put food on the table.

No one cares about how easy or hard it is to install something. IT (or local brick and mortar computer retailer) takes care of all that. Whether or not it is compatible with consistently making money / putting food on the table is way more important.

Until we have Microsoft Office for Linux; Adobe Creative Suite for Linux; Autodeks AutoCAD for Linux; etc etc. not even the janky “Microsoft Office for Mac” little cousin implementation but proper actual first party for Linux releases, it is unlikely we’ll see competitive level of Linux desktop adoption.
