Entrepeneurs vs. investors
Investors just want to get as much return as possible from their previous invested money, hence they'll suggest to sold out and give up at the first sign of trouble, allowing them to take their money elsewhere.
Entrepeneurs want to build something that lasts long, changes people's lives and in the process generates money.
Sims, Chen and co. are entrepeneurs. They may fail, but at least they try. Good for them, for BB and for the market in general.
