Uh huh. I guess that depends on your definition of the word sell. In my view, making money by sharing my ad profile is selling my data. It might not be the raw, unprocessed data, but that doesn’t matter. No EU bank would be allowed to sell third-party ads on the web to their customers based on their personal profiles.
They also can’t “make their bank the default bank”. Unlike the digital world, the banking industry is very well established with lots of competition and money. The big banks have no motive to sell to big tech, and such a big transaction would draw a lot of attention. Anti-American sentiment is high in Europe. Does any bank really want to risk being in the headlines for allowing American tech companies in where regulators explicitly excluded them? Bank runs is how banks collapse.
I hope you’re wrong but time will tell.
