It is endlessly frustrating that companies have universally decided that they won’t let people say “no” to stuff, ever. There are no longer options to reject stupid-ass new “features”, only postponement until next time you open the app/website/program. They’ll continue pestering you for the rest of your life. I realize that my frustration may be a little over-zealous, but we deal with these interfaces dozens of times per day and this is user hostile behavior. There isn’t really an option to just use another service or program, since the entire technology landscape has been commandeered by a few major corporations, and they all enact the same shitty things as a group.
“Got it” is a really weird one too, “Ok” had a hint that you are in approval of what you’re seeing. “Got it” is more of a message of “we know you probably don’t care or even detest this but you have to tell us you are at least aware of our latest thing”.
It is underhanded in the language and has a bit of admission that they know you really just want the modal to just go away.
“Got it” is an acknowledgement while “OK” is an agreement. This is probably a deliberate choice on their part.
