By "acceptable" do you mean actually getting on the store and people buy it? Steam is notorious for allowing utter unplayable shovelware on the Steam store because they don't give a shit. There is no quality control whatsoever, especially with the 2 hour refund window now. That basically meant Steam don't have to listen to complaints because the consumer can just get a refund.
A vast majority of PC gamers on steam don't want all that crap on the store. Over 40% of games on Steam were released in 2016. That is just fucking crazy, an indication of just how much crap is getting on there and making it very difficult for gamers to sort through all the shit to find something actually decent that they want.
The difference between Steam and console platforms is that PC is an open platform, with no one responsible for the content and no brand to protect. The PS4 is a Sony device and anything on the PSN is ultimately Sony's responsibility and reflects on their name. I don't believe Sony has anything close to the Steam refund policy but I could be wrong. I imagine the refund process is a lot more difficult for PSN.
Microsoft had the same problem with the MS Store in Windows 8, and likely still a problem in Windows 10 though I haven't done much in there in awhile. The amount of garbage apps and games in the Store that were basically broken or reselling of existing games/apps was atrocious and it basically killed any hope of trust in their store. No one used it after awhile. There was no quality control for those apps apparently, the complaint process was very difficult to find for an app and nothing ever happened to them either.
