According to ComicBook.com on Oct. 6, Disney is receiving opposition against the portrayal of the villainous Rising Tide organization as represented in Marvel's "Agents of S.H.I.E.L.D." The real life activist organization by the same name is upset and petitioning against Disney to change the label. The fact that it's "fictitious and purely coincidental", as seen stated in most disclaimers of the end credits to TV shows and films, may be seen as something left up to interpretation in this situation.
While the real life Rising Tide is dealing with the issue of red tide, climate change, and fossil fuel issues, they have also explained in detail about the portrayal of the fictitious organization in "Agents of S.H.I.E.L.D." They claim that their motive is to expose governmental cover ups involving environmental issues.
Ironically, it seems that the show turns the tables portraying the "hactivist" group as the enemy and the government as the hero in this case. The Rising Tide environmental organization feels that people will get the two confused and cause confusion among the masses.
Also, the logo used in the series looks stunningly similar to that of the logo or font of the environmental organization.
There are 50 Rising Tide chapters in North America and they are taking action to put an end to prospective confusion, but figure this is par for the course for Hollywood to utilize pop culture to make the government sound like the good guy.
