In real life, al-Qaeda had bin Laden's wallet (and many donations and "legitimate" income). In fiction, to be more specific the latest G.I Joe incarnation, Cobra Industries was a front that used to gather funds for the world domination scheme. So who is padding MECH's wallet? Sure they steal the latest tech, but someone's got be paying for all those helicopters and muscle cars (and I think the secret base in the Operation Bumblebee episodes), right? Personally there are two possibilities. One is a front corporation. Whatever it earns, a portion goes to MECH. Even better if it is a high tech arms company; sure beats stealing. The other is multiple hacked bank accounts. Add a few zeroes in a way that no one finds out, and one can hire all the clueless contractors needed to dig bunkers for hideouts across the world. I somewhat favor the first choice. But I think in order keep the pace of the story going along, I feel that MECH's benefactors should appear in Rescue Bots instead. Have the "legitimate businessmen" put funds aside for "associates".
