I, too, expected to read about all the open source projects from FB. Always surprises me how often the React devtools icon lights up indicating a React-based site. Maybe there are false positives, never investigated. I don't really follow who's using React, but was surprised to see it on Dropbox.com. Wonder how high the percentage would be if it included the library code for all FB projects?
