Nintendo 0%

Doubtful. These numbers provided are completely wrong. Back when files were leaked during this very trial, Epic revealed they had 3 to 4 times more players on Playstations than Xboxes everywhere other than the US.

Accorsing to Statista (accesible on a third party site if you want to avoid registring), Xbox only has 23% of the market (as opposee to PS's 45% and Nintendo's 27%).

I don't like Microsoft, and I agree sideloading should be a thing on consoles too, but they definitely do not hold a majority of the console market, let alone a monopoly.

Tbh I think that data is incredibly misleading. Every single generation of PlayStation has outsold the Xbox of the same generation(yes even the ps3) https://en.wikipedia.org/wiki/List_of_best-selling_game_consoles.

Additionally looking at the faq for that site it appears to get its data via page views. What % of console users actually use the browser? Is bet very few. Especially when you consider the ps5 has no built in browser.

Fair enough.

I think hardware companies should make money selling devices. They should be banned from jailing their users in a locked proprietary ecosystem.

A duopoly doesn't require a 50/50 market share. It simply requires them to be the only real options and to both engage in similar anti-consumer practises.
