What's wrong with their own website? I never said they shouldn't promote it on facebook/twitter, but ffs, companies should use their own website as primary medium for communication. I have no problem creating an account there as long as they don't abuse my data - heck I even have an account, as I preordered the thing. Add a "login with facebook/twitter/google+" button to it for people stupid enough to use advertising companies as their ID-providers, and everyone is happy, including Mark Zuckerberg.

However I concur, while there are open and decentralized alternatives for the facebooks and twitters, non of them have gained significant traction. They can't even decide on a single protocol. But I distrust the facebooks and twitters too much that I'd rather be outside the herd. Unlike the rest. Not following the flock. Have an own opinion and stick to it.
