Why do Athiests use things like Facebook knowing full well Facebook does many immoral things?

[†Archangel TJâ€]

facebook invades privacy, stolen billions of dollars from the public and many many immoral things. Yes you see Athiests on facebook. Why do some athiests claim to have morals and yet use facebook?
I'd thought anyone with morals don't use facebook?
Maurog look at facebook's valuation. their market cap is $66 billion

Their price to earnings ratio is 185100%
Maurog they lied in their financial statements to go public. They falsely advertised their numer of users. They charge merchant's credit cards without consent. They invade privacy of not just their users but all internet sites that puts a facebook 'like' button on it. They have proprietory software. They centralize users data for mining for sell for profit regardless of the usefulness of those data. They try to destroy freedom on the internet by supporting things such as DRM.
@Maurog, the mere loading of like buttons already tracked your IP. possibly reading your cookies too. You don't have to click it. It tracks you even if you don't use facebook, don't have facebook account.
