Sure, open source makes everything rather accessible from a monetary point of view, but you still have to learn things. I almost feel like in the past there were more attempts at making this accessible to the end user, HyperCard, dbase etc, even just BASIC on your 8-bit machine.
Nowadays? Excel/Google Sheets for the most simple case, probably, but if you have to transfer data from/into there or present it differently? Web sites and GUIs aren't that easy, but it's what the users know.
If your point of interaction with a computer is more bare-bones (eg a BASIC/DOS prompt), solutions feel closer, easier to grasp.
Legacy text based solutions that survived are usually much better designed by people who actually spoke to the users.
You pay your admin $18/hr and pay a programmer $50. People tend to assume their place.
