I’ll concede points for stylistic or deliberately informal language, I didn’t want to belabor anyone reading what I wrote to get into the weeds over deliberate “abuse” of the language to convey whatever the author wishes to. There’s certainly room for slang, too.

I’m much more pointing the finger at the more simple things that can be corrected easily, hence the minor irritation, not someone willfully knowing they’re using an informal register. IOW, “could have” to “could’ve” to “coulda” is decreasing formality order, and deliberate, vs “could of” which appears completely unaware of how the words actually work. Break/brake isn’t even comparable. Completely different words. Plenty of room on that one for autocorrect to mess it up though. IMO there’s a difference.
