What you are used to is perceived as best
No-one (or almost no-one) wants to dig around for a third rate alternative to the software they've grown used to.
Also: no one wants to learn to use a first rate alternative to the third rate software that they've grown used to.
Unlike many here most people have zero interest in software, many stare blankly at you when you ask them which web browser they use - it is "the Internet", they are unaware that there is a program that they use to get there.
They buy a PC/laptop and just accept whatever it comes with to use the Internet. Everything else (eg view an image, open a document) just happens - they do not think that programs are involved, even less that there might be a choice as to which program to use.
We are the strange ones: those who think about such things.
