I'm sure that being an app store owner exposes you to the absolute worst just most constant stream of really really awful people doing the worst things, like, forever & ever.

There are some warped incentives too, for sure. But I do think Occam's razor explains why app stores get to be worse & worse & worse: because they are responding to horrors.

I'd love to see some better mechanisms for trust emerge. Software as it is is basically unobservable. You grant or don't grant some permissions & otherwise have no idea what's actually happening. So app stores are the only arbiters of trust.
