I could tell the general path the HN discussion was going to take - free service, free country, etc. - but the bigger issue is all the companies that have been paying Facebook millions for page like campaigns. I'd be angry if I'd given Facebook money under the old system only for them to change the value of what I got from them. The basic takeaway is that the rules that were in place where I might be willing to pay $2 for a like - a person who likes your page sees your post - had to be changed because there wasn't that much user attention in existence. Now it's been inflated to be worth about a tenth as many views, which is what you were buying, only Facebook called it a "Like" and it somehow means something completely different now. I guess the moral of the story is don't invest in anything whose value can be arbitrarily changed by someone else.
