Bundling is illegal in the EU if it used to abuse a dominant market position in one market to gain a competitive advantage in another.

So what Adobe does, or what Spotify wants to do by bundling their own products within the same market, is far from the level of bundling Teams with Office, which is bundling across markets and where Office is extremely dominant.

I don't think the EU is just making up the rules here, there are rules and this case is far more egregious and more clearly in violation than the examples you gave.
