You're pretty much the minority opinion on that one. Homecoming and Far From Home have made so much bank because - aside from being great films due to Feige and Marvel Studios' involvement - they're part of something bigger. We've had five live-action movies of Spider-Man being on his own, and look how that turned out: Two great movies and three poorly-received to terrible ones.
Audiences love the MCU Spider-Man. That's a whole reason why audiences cried at the end of Infinity War, went nuts when he showed up and Tony hugged him in Endgame, or why Far From Home became not only a billion dollar movie and the highest Spidey movie ever, but Sony's highest grossing movie ever.
Sony has a track record of mismanaging the character. Into the Spider-verse is one thing, as amazing as it is, but live-action? Spider-Man has succeeded in the last few years and clicked with so many people thanks to Marvel Studios and the MCU.
