Google makes its money on search+adwords. Everything else they do is a hobby, and it shows. Not necessarily evil, but sloppy produces the same bad result.

Google makes single-digit billions in revenue from the Android App Store. While not explicitly broken out, the info is in their annual report [0], where "other revenues" are a bit over 10B USD (>10% of total revenue):

"Google other revenues consist primarily of revenues and sales from:

• Apps, in-app purchases, and digital content in the Google Play store;

• Hardware;

• Licensing-related revenue; and

• Service fees received for our Google Cloud offerings."

As an aside, the risks section is surprisingly interesting and honest. A recommended read.

They are not being evil they are just using automation to cut costs that ai in reality is not 100% ready yet. Now for google AI works 99.99% is okay but for the developer or user that falls in the 0.01% it destroys them. People are facing similar problems with Amazon, credit card companies and banks etc where automation helps bring down cost for the corporations but causing problems for 0.01% which is sadly an accpetable cost to corporations.
