lawsuits? from shareholders? Unless you have a MASSIVE amount of stocks in yahoo, you have no reason to be ticked... and even then when you put your money into a company, you leave it to them to make the decisions... unless you own 51% or more, shut up and quit whining. really... if you don't like it, invest elsewhere. That's just how it works. Idiots.
Having said that. If you invest 10k in yahoo, you're only gaining a minute percentage for someone else to take over the company and DESTROY the company you invested in. Honestly... IMO, yahoo is PROTECTING the stock holders. These are industry professionals, and I think they did the right thing both ethically and economically. I honestly thought about investing in ms after they announced they wanted yahoo so i could reap the benifits after they gave up and the investors came back. I knew they'd never get yahoo, especially with Googles unseen hand working in the background.
ANYWAY. If you're an investor, and try a lawsuit... Don't bother... you're wasting your money on your bad lawyer.
