Theoretically, yes. But I am confident the EU would find other ways to extract fines from Google in that case.
If an EU company did similar it might not be hit so hard (which would be hypocritical). But that doesn't make this action (a fine for obviously anticompetitive action) in bad faith, so much as it would make the other (lack of fine) so.
Have you any evidence, numerical or otherwise, to substantiate your assertion?
And guess what, most of those big tech abusers are American.
But if it helps with anything, it doesn't look too kindly upon Chinese companies, either.
It can't really do much about European big tech companies since there aren't that many left... and they're in enterprise markets where things work completely differently (enterprises can sue you themselves very efficiently if they're disadvantaged, thank you very much).
And this is EU, which mostly does have them as top priority.
Windows phones tried the Apple approach if I remember correctly when their phones were on the market and it wasn't enough to keep them competitive. They had a litany of other issues to boot, but taking the "walled garden" approach raised the ire of many developers.
this does not look at all even close to a monopoly from Apple.
As far as I see their power in Europe comes from the fact that competition is following them in some decisions.
