On my home network it doesn't work at all since my pi-hole blocks whatever domain they route through for ads.

I've stopped reading TechCrunch since they've put up the data collection popup. It may technically be GDPR-compliant, but definitely violates the spirit of the law. That dark pattern of providing no opt-out for a "consent" form is insulting.

Probably, most people just click "Agree" without bothering with it.

It definitely is not GDPR-compliant, which is also why I don't read techchrunch anymore.
