Twitter still bugs you to create an account to access their content. (Try to see someone's list of followers when you're not logged in, even when that information is public.) Compare with Wikimedia where you don't even need an account to edit content. Further Twitter is still promoting a model where to talk to people you have to create an account on a centralized platform first. ("Want to get support from a company? Chat with them on Twitter. You need a Twitter account for that.") Compare with email where you can email from any provider to any provider. Twitter might be more open than Facebook, but they're certainly not the champions of openness.
