I expect we'll never get a useful explanation from Google for why this incident happened -- abuse teams, like fraud teams, are worried about the bad guys using the explanations to tune their tactics and so tend to never explain anything.
But the details of how Google screwed up here also don't matter. A sudden Friday night suspension of a popular, legitimate app is insane! That possibility shouldn't be in the flowchart.
I get that for malware/spam/etc., it's important to immediately suspend, but I don't understand why Google doesn't take more seriously the very negative harm caused by doing that to a legitimate app. Some notice and appeal opportunity should be required before suspending a popular app by a legitimate publisher.
I'm upset, and a bit scared, but I can't say I'm surprised. This sort of random/erroneous/arbitrary punishment without explanation happens all the time with Google and other major tech companies. And every app developer I've met has experienced _significant_ disruption to their app publishing efforts due arbitrary/random rejections by an Apple app store reviewer, and this has been the case for years, so we can pretty confident that the vendors won't improve unless they are forced to do so.
There needs to be regulatory oversight of the Google/Apple app stores and the negative consequences for everyone else of their error-prone and ruthless enforcement processes.
