I think this is a silly complaint. These are preferences storage. The home directory is absolutely the most logical place for these.

I actually like that there are applications that actually still have preferences. My biggest pet peeves are applications WITHOUT preferences. Careful what you wish for.

I agree that the home directory is the most logical place for files like these, but it would still be nice if they were in a consistent place. That way, if you wanted to delete your preferences for a specific application, you know exactly where to go without searching around. Personally, I think this should be enforced by the operating system instead of leaving it up to the developers.

TLDR. I think the "frameworks" associated with OOP are the expensive disaster. And MVC kind of pees in the face of OOP in my opinion....
