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.
