I listened FB, TWTR and GOOGL hearing. FB & TWTR, they had issues and trying to resolve it. You know what happened after that.
Where as google, they denied and maintained firmly that their search is based on algorithms, no manual manipulation, ready to work with congress or any government authorities…etc.
There were rough times, congress men pushed, but google firmly denied. Some congress men did not agree with google till end.
One thing confirmed, Google is not going to China even though they admitted checking such possibilities internally then and there.
