I just opened FB with the cache disabled and it downloaded 5.85MB (19.76MB uncompressed).
Most of it happens after the page has rendered, which is great, but that's a lot of stuff. There are 13.74MB of uncompressed JavaScript.
its not stealing when the users agreed to it
From the Wikipedia definition[1] of informed consent (in medicine):
> An informed consent can be said to have been given based upon a clear appreciation and understanding of the facts, implications, and consequences of an action. Adequate informed consent is rooted in respecting a person's dignity. To give informed consent, the individual concerned must have adequate reasoning faculties and be in possession of all relevant facts.
What tech companies do is obtain the minimum legally required consent - and sometimes not even that. This may be legal, but it’s far from ethical.
Claiming the average person is able to understand scope of that document— and the likely 1000s of internal documents related to it, and the 100s of thousand pages of related legal code and case law is a stretch.
Document also does not disclose Facebook is subject to secret court orders, gag orders, etc.
— and that doesn’t even begin to cover the knowledge required to understand the related technology and the impact it might have on the users.
Some guys think the web should be usable with a 50€ smartphone on GPRS, and I say no, because there's a middle ground.
So where's your middle ground?
Surprise, many many ppl use facebook in crap laptops, fb is popular with everyone.
You went to the other extreme though. Most people in high-income countries don't even have FTTH.
