"not that hard to do"

Eh, I'm not so sure on that. I often find myself tripping up on the xkcd Average Familiarity problem, so I worry that this assumption is inadvertently a bit gatekeepy.

It's the unfortunate reality that modern tech makes it pretty hard for a person to learn the kind of skills necessary to be able to customise one's own tools. As a chronic tinkerer, I find it easy to underestimate how overwhelming it must feel for people who want to learn but have only ever learned to interface with tech as a "user". That kind of background means that it requires a pretty high level of curiosity and drive to learn, and that's a pretty high bar to overcome. I don't know how techy you consider yourself to be, but I'd wager that anyone who cares about whether something is open source is closer to a techy person than the average person.
