> its ad tech business

now there's the euphemism of the day. Alphabet derives 75% of their revenue from Ads. It is their business.

The article seems to distingish ads from ad tech, stating ads bring in a lot of revenue, but ad tech not. Kinda confused about what the difference is.

I agree it doesn't make sense. How are they supposed to make money from ads without ad tech? They're intimately intertwined.
