Authorities are already cracking down on the use of dark patterns for tricking people into opting into tacking without explicit informed consent. So yes, they will try that, then they will be found out and fined. Then they will be forced to put a big warning screen on front of the fridge just like all those pop ups we now have on the web.

People will still buy it and click through, because they want their junk, no matter what it does with their data.

I can't count how many times my friends and family said "I don't care" when I tried to educate them on how their devices or software spy on them.

People who really care about privacy enough not to buy stuff that spies on them are rare, and becoming rarer every year as more and more kids grow up in a world where being spied upon is normal.

I bet that a sufficiently motivated ui designer could design a system that matched all the requirements of having people explicitly consent, such as scrolling all the way to the bottom of a ToS and typing "yes sell my data" into a box, but also get people to just do it in order to complete an order checkout process workflow.

That fails the explicit consent test for GDPR for what I understand. You can always opt out at any time to.
