I think the issue is not actually how freely given consent is defined, but that these tech giants want to not only offer a useful service, but they also want to be allowed to do whatever they want with user data accumulated through usage of their otherwise useful service. For providing their service, they don't have to use data in the ways that they want to use it. If they were running an honest business, they would be charging the user for using their useful services, not trying to make dime with user data without consent, manufactured "consent", or extorted "consent".

They wriggle and wriggle, instead of running an honest business, where people buying access to their platforms would actually reflect the usefulness and real value of people being willing to pay for a service. That would be a very transparent number, and that cannot be made look more than it is to shareholders though. I think if they did this, then their whole value would collapse massively back down to sane levels. Now they have blown this whole ads and attention machinery waaay out of proportion and will do anything to keep it pumped up. Heck, they want to pump it up even more, because we all know iiiinfinite growth! They would not be satisfied, if their business spanned the whole solar system.
