Don't be ridiculous
The amount of data collected by Facebook is several orders of magnitude greater than Uber gets.
Facebook has 15 datacenters and has spent a billion dollars on the technology. You don't make that many without the data that they need to store.
Uber, on the other hand, has not built any datacenters, and spends less than $250 million annually on hosted equipment.
It is therefor obvious that Facebook is getting more data than Uber.
