they were fine with doing more films. thats not why sony is doing this.
Sony and raimi were trying to reach an agreement over the plot of spidey 4. mainly, they couldn't agree on a villain. and because it took so long, Raimi stepped down, Partly because of the arguments (which happened on Spidey 3 and why Venom was forcibly added into the film, a character Raimi hated and didn't want to use) and also cause there was no way he'd have been able to do it because of other projects he was going to be doing. Sony's agreement with Marvel was they had to make a spidey movie every so many years or they lose the license. So they went ahead without him. and when he left all the other actors left too. So they decided to reboot. put as much distance from Raimi's films as possible.
Basically, its the ultimate example of a cash grab.
