One is creating laws while having no clue on what is end-to-end encrypted. If WhatsApp has access to everything, it is not end-to-end.
This reminds me of the TikTok "problem" where TikTok company had access to everything. Everyone shocked! They replied that is correct, just like Facebook, WhatsApp and others, that is the way the system works.

Still, BBC uses chartbeat, cxense, doubleclick, doubleverify, edigitalsurvey, optimizely, permutive, privacy-mgmt, scorecarresearch, bb-reporting-spi. They are not tracking you... no way...
Those domains are blocked, so I don't know and not going to check whether they will later load Facebook or TikTok pixel. It would not be the first one to do that...
But most sites will, even Ryanair loads Facebook pixel on the last checkout page.
