I'm going to write in good faith, I hope to be read as such.
Firstly, you have not responded at all to my comment on your comment. A sensible and worthwhile discussion may come out of addressing those observations.
Secondly, crimes are in the eye of the judge, but as the accused perpetrator holding my own council, referring to your role in Google and your legal training was a kind of awe. I am a game theorist (the bridge between my applied mathematics and macroeconomics careers) and so I am well aware of the importance of signalling and posturing. I fully expect that a lawyer, schooled and practiced in the manner of approaching a debate, is equally attuned to how what is said and what is not said. The game theorist in me saw something closely resembling strategic pre-positioning, and entirely without second aims, I called it out for what it looked like. That is not character assassination (in my eyes) but just a tiny bit of critical reading of your prose.
If you really want your employer to be left out of this, you can signal that to us all by removing any references to Google on your (already impressive) profile. Or perhaps leave the reference to Google but also ad something to the effect of “leave my employer out of this".
Anyway, returning to the main argument: I doubt any internet behemoth can afford to pull out of the EU and lose access to 740 million affluent consumers because they'd instantly lose revenue that would ruin their bottom line while also giving local European companies a neo terra nullis to develop their products experimenting on their captive audience until they are ready to take the fight back to the behemoths’ home turf.
The internet blue-chips hate being excluded from anywhere because whenever they are excluded from somewhere their revenue drops and some new competitor starts to simmer.
