I think if the legislation ball ever gets rolling two things we're likely to see, because they're low-hanging fruit, are the end of mass tracking on the internet and a meaningful shift in who controls the data gathered.
I can imagine a platform akin to internet banking where you manage your data and its usage.
Something I'd love to see is a "publication" of big-data algorithms. A private entity designs the algorithm for profit and leases it and you run it in your (trusted) environment, owning both the input and output. Nothing leaks.
Its "this person watched this, so they would also be interested in this video and this ad." You can't make this anonymous and near as useful, and it is currently YouTube and Google's premium money maker.
Most other data is already available with a little work, providing the data you describe doesn't help competition that much.
That's what I meant by cross-platform linking.
> You can't make this anonymous and near as useful
I argue that you can. Anonymity is about not linking you, the physical person, to your online presence. An online presence can be tracked and profiled, without the invasion of privacy. It all depends on what data is collectable and who has access to the data. An algo provider doesn't need to also control the data it is used on, it just needs access to training datasets. There are technical solutions to all these problems, but it's a political solution that's lacking.

Well if it doesn't help competition, how useful can it be?
Everything there is taking place on YouTube. Ads can maybe be a cross platform, but even that isn't necessary
>I argue that you can
It can't. Knowing what videos I have watched in the past is very useful. This can't truly be anonymous and shared.
>Well if it doesn't help competition, how useful can it be?
You are the one arguing that releasing this data solves a problem.
