That the key part that I call BS on. Minority of sales (less than 50%) While less than 50% they still are well over 30% over all and if you move it just upper middle class and up it gets even closer to 50. The other big part is they are part of the duopoly. Top it off Apple is using its massive mark power in the mobile OS to leverage its power in other markets.
Limiting everyone to say Webkit is not a market advantage for anything but webkit. The bigger part is Apple using its massive power in one market to squeeze others out in different markets.
Market share and duopoly doesn't really matter with the DMA.
What matter is
- revenue in the EU
- number of (business) users
- market value of the company
- number of EU countries they're in (more than 2)
