Greg is bothered by Plaxo scraping your friends’ email addresses from Facebook. But I think he’s less bothered about the automated downloading of them from Gmail and other services. Paul Buchheit points out that the latter is just as much a violation of Gmail’s TOS as the former is of Facebook’s.
Why is doing it the hard way more of a violation of privacy than doing it the easy way? Just because Gmail has an API for it and Facebook tries to hoard the data for itself, is there a difference?
The way I see it, if your friends are making their email addresses available to you through Facebook, then trying to put those email addresses into a place where they are easier to use isn’t a violation of privacy. It would be a violation of privacy if Plaxo made your friends’ email addresses available to anyone else, of course.
Am I missing something?
