> many of them have believed the platform’s timeline for development and implementation of it has been “too aggressive,”<p>Publishers can't get used to the idea, that they don't own the conversion funnel anymore, without knobs and hooks provides by cookies, it is hard to know when to upsell, when to show an ad, when to show more ads. I don't feel bad for them, but on the other hand, I don't like the idea, that all these control will be transferred to Google. Without 3rd party cookies but with its scale of search, ML capabilities, Android devices, etc. Google will be the only one who can track users cross site reliably.
