There’s a misunderstanding of what the problem is for page owners. Facebook is double-dipping. Page owners had to earn their likes, sometimes using ad campaigns and other Facebook sponsored methods to do so. They put like buttons everywhere on their site, on their emails, on their blogs. They spread the Facebook brand far and wide so they could have a regular-people way to reach those who cared about their brands.
And now Facebook wants to charge again to reach those fans that page owners have already earned.
You would be upset too.
