This can fuel better ads. So consolidating this stuff further could have that effect.
To me it is so creepy how much of even our casual thoughts outside of facebook now are going into facebook servers. There's just no escaping these data addicts. That's the concern.
Facebook does not have a monopoly on anything, and neither does Giphy.
Especially now, when you have companies like Giphy being tied into services across the globe and providing a surprising amount of data about users and usage patterns, the idea of monopolies is completely obsolete. It's time to bring back the idea of companies not being allowed to much reach, power and control over all aspects of our lives, as well as being able to use it to assert control over competitors and users alike.
