Note: If you don't want to deal with stuff like this, I recommend you download and use it from F-Droid client or Accrescent AppStore.
Update: The app returned to the App Store.
Hopium question: Can Google be sued for this as anti-competitive behavior and fined for "lost revenue"?
In theory yes. In practice or will require enormous resources to build a case against the army of layers that Google and the other giants can afford. I believe only the government now is big enough to do it, with the antitrust law.
Which I'm pretty sure they're already gunning for Google, so this might be more evidence for their case.
Hope so. I’d imagine their lawyers will see this with joy.
The answer to "can X be sued for Y?" is always yes, you can sue anyone for anything, this doesn't say anything about whether you'll succeed.
You can install any apk on your phone (even unrooted) and there's alternative stores such as f-droid, so why?
