Google/FAANG have no real point of control anywhere in the process of how the sciences operate. Scientists publish in journals, while social media, search, et al. are handy but not something that guides their research or their consensus.

The real gatekeeping comes in what research gets grants and funding, but if you look into what's happening there, it's not comparable to the Church proscribing things - it mostly means that the DoD, petrochem, and a few industries have outsized influence on what research is done.
