Let's be clear on what the deal was. Sony will allow Spider-Man to be used in an unannounced number of MCU films in exchange for Marvel co-producing a Sony owned Spider-Man reboot film. The part about other characters crossing over was still being worked out at the time the deal was announced. We do not know what those terms are.

Let's also examine the original deal. Sony has a license agreement with Marvel which grants exclusive live-action rights for Spider-Man and his related characters. That's what they paid for. The new agreement - as announced - reduces the exclusivity a little. While Sony would surely like to include more characters, Spider-Man was the only big bargaining chip they had. Sharing characters is always possible with amendments to the contracts, but I have seen nothing to indicate that Sony and Marvel are sharing everything. Feel free to believe otherwise, I'm basing my beliefs solely on the official announcements and not the speculation. Time will tell.
