This is some "my uncle works at Nintendo" bullshit, but a friend who has friends at Sony said that a) Sony 100% planned to walk at Disney's offer regardless of what they initially said and b) this is just the first round, and that Disney leaked this news to bring Sony back to the table, and they almost certainly will.
It's basically the same situation that brought Spider-Man back to Marvel in the first place: negotiations between Sony and Disney break down, the news leaks to the general public, and pushback from the fandom restarts negotiations. I'm not saying people should start #HoldTheLine or some shit, but I wouldn't be shocked if in a month or so Disney and Sony work out a deal.
That or Disney just straight up buys the rights back.
