"No Thanks" isn't nearly as bad as "Maybe Later" as the only choice other than "Yes", where "Yes" means I agree to be spammed with marketing material, notifications, or accept a paid service I don't want. "Maybe Later" means I'm going to be asked again and again and again if I want this thing I don't want. If they want to have me click "No Thanks" and they accept the No, that's fine with me.
These are intentionally done by marketing dweebs to increase click-through I have to assume, because you have to spend extra time trying to find the "fuck off" button.
