Absence of rich support isn't indicative of a rift or some drama. Business doesn't have to be juvenile or like high school cliques where you've a new best friend every week. Sometimes business direction just doesn't line up, and that's irrespective of whether or not things are possible or even sensible.
Capcom's big push the last few years has been games clearly targeting Xbox One / PlayStation 4 tier specifications, of which the Switch is not. Their biggest games are Monster Hunter World, Devil May Cry 5, and Resident Evil 2 Remake (alongside now Resident Evil 3). All three of these are technically impressive games pushing late generation image quality on the most powerful home consoles available. I'm not at all suggesting it's impossible these games could run on Switch, more that the gulf in processing power clearly puts the Switch in the backseat of priority when it comes to porting these games. Even if builds are possible (and I personally think for some it absolutely should be, namely Resident Evil 2), it may simply not be in Capcom's interest to spend the time and money porting them across (even outsourcing) when they've other priorities. Resident Evil 2 Switch is not at the top of their list, Resident Evil 3 Remake with multiplayer is.
The absence of a Switch exclusive AAA title from Capcom also isn't indicative of a rift. Business changes, priorities change, and again it might simply not be in Capcom's interest to commit dev time/resources to a game built exclusively to the Switch despite how well titles performed on the 3DS so many moons ago. Like a lot of developers evidence in output suggests that Capcom's main focus, as in where they're spending most of their money, is on the technologically leading platforms. And that they've found so much success there just encourages them to keep doing that.
As for the ports we've got and their stupidly high over pricing...that's a Capcom thing in general, in my opinion. They price gouge on most platforms, even if the Switch gets stung the worst.
But yeah. I get it's disappointing that Capcom hasn't come along with exclusives of massive support from ports and whatnot, and it seems like they did a better job of this in the past. But I'd also say evidence suggests not a rift, so much as them finding incredible business success on other platforms with a production focus that isn't perfectly aligned with the Switch's capabilities. Sometimes there's no real juicy story, just different business ideologies.
