I like the responses in this thread... some are pretty funny.
The Switch has a somewhat decent digital library already actually (over 100 I think, I know a drop in the bucket to Steam, but some posts make you think there's only 20 games to pick from), large enough that it can't even display all the games in it anymore (unless this has been fixed, older games can only be found by searching for their titles).
Part of the reason is how new releases are handled, on Switch, every new release is essentially spotlighted and shown to the entire userbase. On Steam not so much.
Now, I get Steam has tons and tons of games, and many are higher quality, but should that really matter to the extent here?
We're talking about potential sales here as low as the 100s (up to 1000s)! Shouldn't a team with a game selling that few copies not be a little offput by the platform? Clearly something went very, very, very wrong if you release a game and it only sells a couple hundred copies. I think they needed more advertising on PC personally, develop more interest in communities. Ultimately to me it sounds like on PC they designed a product the audience did not care for, perhaps this type of game doesn't do well for a PC audience and is missing many features they expect to be standard.
