No, a conspiracy has a very specific definition that has gotten lost in all the noise:
noun (plural conspiracies)
a secret plan by a group to do something unlawful or harmful: she served five years in prison for taking part in a conspiracy to sell stolen art works.
The key is that it's a secret plan. People have to have gotten together to meet, in secret, and agree on a plan. This is why true grand conspiracies are so rare: it's hard to get a lot of people together in one room, get them all to agree on a plan, and get them all to keep it a secret. The more people involved, the more likely there will be a leaker.
Criminal conspiracies are quite common though. Of course, those can involve as few as 2 people making a plan to commit a crime together.
