The site is one giant ad
It's a storefront.
it bans users from the forums willynilly
Forums are moderated by publishers/developers, and you only get banned for the game's specific forum and they only have the power to ban you from the game's specific forum. You have to be a very annoying repeat offender to get banned from the whole of the Steam forums, and what the fuck does that even matter because it's just the forums. Are you not there for the games?
it dumps triple A biased sales at you at the expense of indies and foreign devs
It's only natural a store would recommend games that are popular, and what's popular is usually stuff that's heavily marketed like AAA games. Steam hosts many events and has many features for finding indie games, and doesn't have any bias for showing the games of any "foreign" games even though I wish they would because I would love to filter all chink and gookshit from the store.
it plays a cascade of nonsense you have to close for each page
The only thing it shoves in your face is the news popup when you start the client, which can be turned off. I have no idea where you're getting that it shows you ads for each page. This is just factually wrong.
it forbids you from moving even simple games to another directory as an always online DRM
The only complaint that's valid. You're allowed to move games to a different drive. You're not allowed to move individual games to their own individual folders because of the way Steam functions.
Yeah, English is definitely not your first language. I never said it was as good thing, but "no Japanese games allowed" is a very damning but retarded and false statement. Stop posting if you can't even communicate properly.
