We actually do understand and want good SP content in fighting games. Just because we play seriously doesn't mean we exist on some other planet devoid of empathy for more casual players. Games not giving casual players stuff sucks because it's less people enjoying the game. It's less people even trying to play the game period that might snowball into being competitive. It's less people buying the game and lower sales hurt us too.
It's not like we went up to Capcom and were like "Don't put in arcade mode." There also aren't that many people saying "fuck you, got mine" either. It's pretty well understood that they hurt casuals and us all in the same series of shit decisions.
I think you are overestimating how many people who "represent the FGC" (in these topics) share that logic. I was pushing it from the beta days, Capcom needs to appeal to casuals, put in more SP content, don't worry about lack of 1F links and extend-a-combos from jabs, what's important is growing the base... but the truth is there have been tons of "fuck you, got mine" posts here regarding SFV. In fact, that often comes across as the general sentiment. You don't like it? You have no right to complain, look at that other fighting game's problems! That poster wants arcade mode? I bet they wouldn't even buy it!
When people are seriously suggesting the last-minute, sorry excuse for a survival mode that they had the intern slap together qualifies as any sort of worthwhile single player experience (or anything less than frustrating), it shows a toxic, either condescending or head in the sand attitude that quite honestly isn't being helped by Capcom's addressing/lack of addressing of key issues since launch. The saving grace is that the FGC in general--offline--has improved a lot. You don't hear dumbass statements like "if you want arcade mode, VS CPU has been in for months!" offline. I loath SF4, hate-played it for literally close to 1,000 hours, but I knew that it didn't just bring people in because of nostalgia -- it brought in a lot of
new players, in part because it offered a lot of content. Then Capcom said "with SFV, we want to bring in a lot of new players" or something like that, then they release the most anti consumer fighting game they've put out in some time. Can't make it up.
Most likely, outside of Punk pretty much all the top players have been competing since at least the IV era when second place wouldn't event cover the plane ticket.
SF4 was a different game, that's apples to oranges. I'm talking about SFV specifically.
I witnessed this with my students this past week when introducing them to a bunch of older fighters. They kept shrugging off whenever I asked if they wanted to see Darkstalkers. Then, when loading up SamSho 2, a couple of them confused Cham with Felicia and asked if SamSho was where she came from. Then I booted up Vampire Savior and they were like "oh, wow, Felicia, Morrigan, Hsien-Ko, and John Talbain (I'm just as confused as you are) are all from the same game!"
Hilariously, the fighter they were the most excited about wanting to keep playing was Third Strike.
Good kids, fighting for the future.
