Well with Facebook you sign up and agree to a big EULA that presumably allows it. If I visit site A then site B, site B shouldn't be privy to whatever I said at a different location without agreeing to share it.
That's customizable isn't it? When I text I'd much rather have emoticons than a newline, whereas it's opposite with emails, and I've found that Swiftkey does a good job switching between them (somehow).
His point there was that not all ads are evil. As someone who has purchased things based off of Facebook ads that I've seen, I share his "lack of hatred" for ads, provided they're not annoying or malicious. If they keep services I like free or cheaper as a result of their existence, then I'm not going to complain about them too much.
