Google's core product has always been advertisement. They sell advertisements to companies looking to advertise, and they bring in tens of billions in revenue from that business. In effect, their core product is you: they're selling your eyeballs.

You claim they've ruined their core product, but it still works as intended, never mind that you've confused what their products actually are.
