Disney sues when others are trying to profit off of their property without permission and rightfully so. If you have an actual case where Disney sued just to be mean and cruel to someone because they can or brought a case out of boredom for kicks, by all means share it. Disney is a company extremely dedicated to their public image and brand. and I have no objection to them protecting their property.
People who keep bringing up the prior lawsuit also keep neglecting to mention that it was settled out of court and by all reports, Marvel really did not have much of a case. The whole issue of whether having close approximations of characters in a videogame like CoH was never tested in the courts back them. The legal analysts who brought up the "crayon" argument I believe had a very compelling argument that still holds true today.
This is just my opinion here, perhaps this whole issue of copyright being decided in the courts is something that does need to happen. Not here on Homecoming specifically, but somewhere. Companies like Disney, Marvel, WB, CBS and other copyright holders who throw so much money at lobbyists to get copyrights extended into perpetuity are doing far more damage than good in my opinion. This is stifling creativity and imagination, and that is not a good thing.
