Of course they tune their page so that search crawlers can best index the information, so does everyone else on the web.
However, they also provide an API, with clearly defined terms of use, which you may use to get information. Basically your complaint boils down to you don't want to use the methods they've set up for you to access their data, and you're complaining about it.
As for comments about fair, true spirit of the internet what have you... I don't think the true spirit of the internet has ever been everyone has to give everything away in every possible imaginable way. And, in the end, it is Facebook's data, they make that clear before you ever start adding data to their servers. So does just about everyone else who allows you to submit data to their servers.
This shouldn't be confused with how difficult it is to remove data and accounts from their system, which is a giant pain in the butt, or the fact that they've made drastic changes to the public nature of the data after keeping it private for so long. That's all just a giant mess.
