It's often very open to interpretation what constitutes a market, what constitutes bundling, what constitutes dominance, what constitutes monopoly, what even constitutes a product. There's neither such a thing as clear-cut definitions, nor even common sense (since different people's common sense can be diametrically opposed).
It's things as basic as: is a Sony Walkman with headphones one product or two? What's the difference between Sony requiring you to buy headphones together with the tape player, or Android requiring Google to be the default search? Is "portable cassette player with headphones" a single market, or are "portable cassette players" and "headphones" separate markets?
There's no such thing as "just follow EU regulations". Google and other observers can genuinely believe it's following them, while a specific EU court and yet other observers can genuinely believe it's breaking them.
