I imagine the value that Google gets from chrome extensions is a small fraction of what they would get from Android apps.

They're not going to be able to spend millions of dollars to fund better human moderators and tools for the extension reviews when a typical extension brings what, a few cents for Google?

They probably can't justify the resources to do the sort of specific feedback that would make this process much better.

Even Android App developers face the same thing. When they upload their app to the app store some bot looks at it, and can reject it for whatever reason and only provide a vague explanation. I've seen stories on /r/androiddev of developers apps getting rejected for uncertain reasons, or even having their whole account entirely banned. Unless you are a massive company like Netflix or Spotify you will have not way of contacting a human for support.

I've thought of messing around with developing an Android app and uploading it to the app store just to gain some experience and try something different, but the fact that my whole google account could be banned just because a bot thought my app was bad for whatever reason is scary.

I think that you're assuming that the number of apps that can be reviewed by a human remains constant over time.

If Google hires programmers to do the review process, they can identify patterns, develop new techniques, and build tools to accelerate the process.

Additionally, I bet that they're expecting the value of the Chrome store to increase over time, which compounds on the effect above.
