Both Anon and the cartels being highly varying organizations, and this it being impossible to speak for the entirety of either group...
I think the general feeling seems to be that neither side lost, but neither side is going to push it either.
Anon apparently got their member back, but a great deal of those involved (identifiers like "most", "the majority of", etc. being difficult to apply to Anon) also seem to realise that they couldn't have opened this up into an actual "war" without significant bloodshed.
At the same time, the Cartels didn't get any contacts blown and made vulnerable, but they also acted in such away that suggests they at least recognize Anon's potential for troublemaking, even if they don't think of Anon as a threat on the same level as rival cartels or the Mexican government.
