Trying an orange is a lot easier than creating a boot USB, copying all your files over to an external hard drive, installing a new OS, fixing weird things like the graphics card having crap performance or the laptop screen brightness not dimming, learning the weird 3 letter file structure, being bogged down by apt-get vs snaps vs flatpak and adding repos (why not search and download an .exe like a normal OS), realizing that your more specialized programs don’t work, etc.
Besides, it’s not just ONE person, seeming everyone says it every time a lemon has a scratch or a blemish or too many seeds. And then they dramatize it by calling it an “abusive relationship”.
