If you're going down, never admit it. Ever!

Rule #36 of The Supervillain's Guide to Super Villainy:

• If your plan for world domination, has gone down the toilet and is dragging you with it, keep kicking and screaming. And never, ever admit defeat! In fact, pay off everyone one you can, to act as if you're still on top.

If someone comes along with a smarter and better plan than yours, deny it, ignore it, bribe people, and always butter up the stupid and gullible masses.
Of course, it does help to have built up a mass following of mindless minions, over a few years.
Remember, Supervillains are smart and resourceful.
Take Micro$oft for example; Bill Gates started building up his world domination plan, rather successfully. Millions of people fell for his first few innocent drafts. After all, it was easy for an average person to use. Well, easier than most other things available at the time. And by the time Bill introduced exorbitant licences, people were already hooked, too brain-washed to realise their folly.
But Micro$oft hasn't been the only option available, for a long time now. More and more people are starting to realise this. They're also starting to realise that the other options out there are free, easy to use and you actually get a response to your bug reports. now
But never fear. In true Supervillainy style, Micro$oft are not going down without a fight. They still have millions of followers out there, that they'll keep milking for a good few years. Take a leaf from their book Supervillain trainees. Just make sure that the leaf you take, isn't the only leaf in your Supervillainy book!
