Some opinions on this article are naive but I do agree regulation is an important step forward. Unless there is regulation like the Fiduciary Rule in place for tech companies, they can say "we are making the world a better place" however and whenever they like but they are not obliged to actually do it. These companies will be your friend if there are economic incentive to do so, or it would incur legal costs if they weren't to comply to their role as a fiduciary to their clients.
