Facebook is a for-profit company and you've agreed to their user agreements. They use proprietary software, they store your data, and they aren't liable to what happens to your data, much less liable for keeping you happy in exchange for you doing absolutely nothing but consume.
You aren't entitled to anything from them. Stop using it if you don't like it. Use something else or create something else. Life is not going to be served up for you on a platter without you doing anything for it, from the government, much less a large corporation which has no accountability towards you, who so blindly signed up, supported and agreed to let over all your personal content and social connections over to a for profit company. I'm confuse as to how people can feel this entitled without deserving anything due to not putting any work or ethical and moral reflection on how you use the Internet. Knock it off.
Sorry, your letter pissed me off. It pisses me off that it is #1 on Hacker News right now. Knock it off, everyone. I am a very liberal person but this sense of entitlement from middle class Internet users has to stop. It is the reflection of a society that consumes far more than in produces.
Excuse my rant.
