well as overwhelming majority of google's money flow is in Europe
Google's revenues don't come majority from Europe. Europe is about 20%. That's smaller BTW than the 27% that Google had in China when they started fighting with the Chinese government. They halved their Chinese revenue but didn't have to impose censorship. And that required the Chinese government funding a major non-Google competitor in China. I think the Spanish government would have a harder time for a variety of reasons.
All of these have vested interest in google staying in Europe.
That's right. In terms of the monopolist position that may not be possible. Google may simply decide they would rather go offshore than agree to European governments breaking them up. This is a company with a track record of doing exactly that with China. And as you can see Spain is getting ready to cave. The EU governments are losing. "We will shift the news Spanish citizens consume away from news produced in Spain" was a fairly credible counter threat.
Now obviously if the governments are concerned enough they can win a war against Google. But given that Google has a monopoly in Europe because their citizenry likes Google, backlash wouldn't be shocking.
Companies win fights against governments all the time. Ask Latin America about American Fruit Co. if you want a really extreme example. The USA governments has had problems with OPEC (a cartel but close enough) for 4 decades.

As for climate denialism I'm not sure how that contradicts global culture. That seems to support it, showing people gathering not by geography but by political / idealogical affiliation.
