Not in a monopoly or oligopoly, which is the common case in markets with high barriers to entry.

If this a hypothetical? I can't think of any monopolies that I need to do business with that only do business through an app.

My bank's android app has more control over my account than any other way of interacting with them, including going into branches and posting forms. That's not strictly a monopoly but I'm on my fifth bank and they've all been similarly rubbish.

Huh, interesting. I can't think of many notifications I would want from my bank. I've got an alarm for if my balance goes under a certain threshold, which I guess could be handled via a notification, but IMO it is easier to just make the threshold high enough that I can treat it as a "check-once-per-day" thing, and get the notifications via email.

As a UK customer, I use Monzo bank and have pretty consistently had good experiences. They are a new bank. Recieving international money transfers was the only bit that they didn't support.

For those with infinite time or for whom this is a single issue, yes. For the rest of us, disabling notifications isn’t too hard.
