tired: esports aren't sports because they're video games
wired: esports aren't sports because they're proprietary artifacts tied to one specific manufacturer, rather than a set of rules anyone can make equipment for
I think this post genuinely hits upon a big reason why games-as-sports will never be as ubquitous as physical sports, and also the only reason why game publishers pour so much money into trying to make it happen; Game companies want a sport that they have a monopoly on, and players don't. Monopolistic practices are antithetical to the kind of accessible universality that makes a sport something anyone can pick up at any time or start their own organization for. Game companies will never allow that, and so we'll never have it.
I mostly agree with this. There are definitely sporting organisations that have grown into near, or actual, monopolies over time.
But most importantly, none of them started as monopolies. Which is the norm for esports.
