Think about it. There are two possibilities:
1) Facebook is trying to ensnare startups into its web of twisted lies so it can destroy them.
2) Facebook is just trying to work out a mutually beneficial deal with startups that want to leverage their technologies.
While #1 is possible, you have to admit that #2 is the more likely situation. It's like Sagan said: "Extraordinary claims require extraordinary evidence."
I'm sure you know what you're talking about, so this should be pretty easy. Give the startup community sound logic rather than speculation.
