All these comments explain why there's still general public resistance to Linux - quite apart from the fact that many people think "the computer" = "Windows" and have never heard the phrase "operating system", let alone can tell you what it is. Mint, Solus, Debian, "Ubuntu with a smattering of Devuan and Slack" and 1,000 more. And that's before you get onto "forking" to make things work.
How on earth are the general public supposed to know the difference and make an informed choice? Yes, I get it's all *nix, but most people aren't and don't want to be techies, just like most people who drive a car have no interest in and couldn't tell you about torque points or what "revs" actually means, or the relative effects of different PSIs. Windows, for better or worse, just switches on from the get go, you create an account and you never have to worry about anything else "technical" again, except occasionally to reboot for an update when it prompts you.
Also, I've used, or tried to use, Libre Office. I have a few hundred Word docs dating back a decade or more that include multiple small images, anything from half a page to 60-70 pages. Certain headings in bold text. All in the same font style and size. When I last replaced my computer (to Win11, boo hiss), Libre Office blew lots of the formatting out the water - at random. Some bold headings were now partly or non-bold, and some in a new font. Text that had been beside some images was now under them. Some text columns and small inserted tables weren't displaying correctly. And these are fairly basic features and functions so it should have been a seamless transition. I lived with it for a few months then bought Office again.
I hate all the prompts to use Office 365 (I just want a single install and I don't need to access anything from elsewhere except email), and backups to the cloud (I've got far too much data for that to be affordable so I'll stick with my various removable hard drives). But unless *nix can establish itself in the office (pardon the pun) environment so that people can become familiar with it, and until the 'every developer makes their own version' number of products can reduce to - at best - a few product names, nothing is going to change in the mass home market.
