Though I think Zuckerberg has done a good job continuing this despite the leaks (at least that's what it seems like externally).
It might not be just the company that changed, but the employees too (which may have forced Google to change policy as a result).
Both are trying to do things at massive scale and dealing with the problems associated with that.
I think both do things I don't agree with, but are generally unfairly vilified most of the time by their failing competition (the press mostly) and weirdly some of their employees. The sense I get from this is it's mostly political tribalism (affects both far left and far right with different grievances for each).
I don't personally like the ad-driven model, so with the exception of YouTube I avoid their products where possible.
