I find it a hard sell to say that any — and every — user should learn every platform of choice they use well enough to be able to modify it.

In fact, I might say it is our duty as developers to make sure the default version of our program is good enough that almost no user should have to change it.

And I believe Windows accomplished that, at some point. Then some asshole decided to add ads to it all, just to squeeze a few more cents out of the users.
