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.
And this is EU, which mostly does have them as top priority.
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.
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.
