Counter-Conspiracy

There is of course much talk of conspiracy on this site. Most of it is of evil bad meaning governments, companies individuals etc. Is it likely that at the same time there are groups fighting and conspiring against this of equal or close to power who are fighting for what we would see as the right thing, such as peace equality etc?

Anyone have any evidence of this? Would just be good to know that not all conspiracies in this world are a bad thing.
