Earlier quoted context omitted.
Is Play Store or Steam any better? All these stores are basically little monopolies with zero incentive to not suck. They also suck from a user point of view. Search is terrible, they’re full of shovelware, etc.
Steam isn't a monopoly, it provides ease of catalog and access. smaller companies can still sell on their own website or any other number of storefronts. The gatekeeper here now is generating MS signed apps.
And Valve saw that coming some time ago, and invested in making both Steam and the games sold through it run on Linux.
