But it also means access to all of Spider-Man's characters and it stops the Sony spinoffs from happening
That's not worth 4B. Not even worth 1B. Disney pays 4B for Spider-man live action movie rights and their stock will take a nose dive the day it's announced.
^ This. The property becomes toxic with negative returns while in Sony's hands. It completely erodes their bargaining power. No other studio in their right mind will examine and determine that without the cards Marvel Studio's holds that they'd be anymore successful. The fact that the only recent success with the character was due to a collaboration with Marvel Studios does not reflect upon SPE well at all.
Getting Sony to come to table to create a situation where the character's movie rights are intertwined with the MCU was a masterful play. Disengaging the character from the MCU in an attempt to go solo will have at best create diminishing returns as in the GA's mind space he is part of something far larger. Sony got played hard, and their studio executives' egos blinded them to this.
I still think that Disney could have gotten more at that time than what is publicly known. Who knows though, they may have amended the contract to not allow the rights to be transferable or whatever else.
However, I see now how this deal put Sony in a hard place. Taking Spidey out of the MCU only to reboot him again is a bomba in the making. With Hirai gone and Yoshida in, it's not too far fetched to think a deal for full transfer of rights could be reached. Especially if Venom bombs. The timing may work out too (i.e. Venom bombs end of the year, Fox acquisition closes end of the year, Disney execs more willing to enter negotiations to reacquire spidey live action movie rights because it won't risk anything).
Yoshida is much more about turning Sony back to what it was in the 90s than a movie and entertainment house. I think his focused will be on getting Sony to the levels that it was and to challenge FAANG and Samsung. He wants Sony at the forefront of self driving cars and robotics. Having a division that is volatile and oftentimes posts losses is not what Yoshida wants.
Fool called it (i.e. Gaming/Music good reasons to buy SNE, Pictures/TV reasons to stay away from SNE)

Finally let us not forget that Sony stock shot up when it was speculated that they were selling off SPE.

Yeah, but it is a big if right now.
That's a huge if. Even if AT&T gets TWX with no strings attached we are still talking about a huge bidding war that may not serve CMCSA or DIS (or FOX for that matter). DIS is not gonna give that up and the wheels are already in motion there. CMCSA's only win in this scenario would be to drive up the cost and lose the bid (therefore making it harder on DIS' balance sheet).
CMCSA would be better off trying to buy up SPE, LGF, MGM, Paramount if they are after content (and LGF also owns Starz for distribution). That would be significantly cheaper provide them with significant content that they could use to scale and compete with FAANG and DIS post Fox acquisition. We are talking about Ghostbusters, Bad Boys, Bond, World War Z, Mission Impossible, Hunger Games, Twighlight, Saw, John Wick, etc etc. Those are all franchises that could easily be revived or put exclusively on xfinity. They could also leverage them in their parks (Saw and World War Z would be great fits for HHN and other franchises could easily get permanent rides/lands).
And they better get a move on that too because Amazon is very interested in LGF. CBS/Viacom may also merge and make a play on another one
