I’ve never found it more convenient to use Steam or another store over piracy so it doesn’t make much difference to many.
Some of the games I do own on Steam now don’t work either, so it’s not like it’s an amazing store.
But if it’s inconvenient to download a different client just to buy a game then you’re just lazy. It’s not like you have to subscribe to it, it’s just a click and 5 minute wait.
