It’s not just apps, either. There is frequently a “less disruptive” option for any major action; for instance, you can “delete” files by starting with the instantly-reversible "chmod 000", and after some period of time you actually go ahead and "rm -Rf". If, in between, a panicked user E-mails you back and says they really needed those files, you undo your "chmod" and instantly fix the issue. Why should anything on the App Store take days?
Class actions suits have to show damages, no? After the money is refunded, what would the plaintiffs allege?
And certainly when fraud is detected some refunds will occur. So they set the tolerances such that they can pay those refunds with the fees they extract on the other side of the curve.
You'd be amazed at what a few billion in the bank will attract, especially when it's cheaper to settle than litigate.
First of all, if it's actually fraud that totally doesn't scale.
But in a more nuanced case, look at the iMessage App that allowed people to send images that looked like a stock Messages blue bubble. Good idea for humor, not so good for non-trolling UX. Apple pulls it but gives the developer a week to see if there's any way to salvage the situation to ease the heartstrings and pocketbook.
IMMEDIATELY calls go out to download the infringing app, several thousand more than anyone who might otherwise (full Streisand effect)...
Then imagine that app actually has Malware! Lots to think about, and if people hate on Apple for this, fair enough — as an iOS dev it's tough to defend. Really love Dash. Hope it gets straightened out. 8 years in on the platform and you can do a ton of things you couldn't do back in 08, and vice versa.
