I believe they would target conservative sites. When living inside the liberal bubble, conservatives represent threats and a way of life that is not natural for a lib.
This is actually another example of hypocrisy. The left purports Republicans to be the powerful rich just stomping all over the little guy. Google is a prime example of the powerful and rich. The conservative, which now includes the blue collar/middle class folks the dems threw out of their party, are the little folks the rich and powerful want to stomp out.
Liberals consider their political ideology the source of good.
So liberals at Google censoring conservative content, punishing individuals specifically (like cancelling Dr. Jordan Peterson’s email account in addition to censoring his Youtube channel) and skewing results to suit their side is MORAL to them.
