They haven’t provided a source! They extrapolated from data they don’t understand! The criterias for companies to be analysed under the DMA are public and the PC video game market just doesn’t fit! The reason Steam isn’t on the list isn’t because it’s not a monopoly, it’s they the industry they I operate in isn’t taken in consideration by the law.
You could be the only online windmill hat seller, the EU wouldn’t put you on the DMA list because you wouldn’t sell 6.5B euros worth every year and your market valuation wouldn’t be 65B euros. It doesn’t mean you wouldn’t have a monopoly!
Heck, Valve doesn’t even have a market valuation because it’s not public! They’re evaluated to be worth less than 10B USD and it’s purely surveillance, that’s a long fucking way to the minimum threshold required be the DMA isn’t it? They’re still the biggest player in the PC video game sales market.
