I don't think they're working for Google but I'm convinced that they're trying to setup their own advertising business

Trying to get some of that sweet ad revenue money

but Google controls so much of everything that of course they're indirectly funded by Google, so it may look like they're working for Google

In this Tecnofeudalist reality that we live in, we all indirectly work for our feudal lords Google / Meta / Amazon. We are granted their grace and allowed to exist in their server space and use their internet cables. In return we have to work the land and give our data as a tribute.
