Ha. Silicon Valley can be really pathetic sometimes. As an employee, you should really go with whoever pays you more. If employees of another company want to shame you into accepting a lower wage why should you?

Silicon Valley is always talking about "changing the world" while building pointless apps that will only exist for 5 years at most as they try to sell to a bigger data mining company. All in the name of "being passionate about what you do".

Fuck that. Starting a for profit business is mostly always about making money, so as an employee you should try to get as much money as you can from them. If you start a company and really believe you are changing the world or making the world a better a place, then make it a non profit. Otherwise, get your head out of your ass.
