Strictly speaking, it is, but you do it with money, not ideas. Offer the Nokia board $20 or $30 per share and they will throw out the management and institute your own faster than you can say "revolution."

If you had an absolutely iron-clad plan, it's not inconceivable that you might be able to raise the required money for an LBO.
