Due to their centralized nature, and the result of being located in the US as one of the largest communication platforms, Twitter has become the enemy. It was probably not their intention to become the enemy, but that's the consequence of being located on US soil and being one of the largest service providers (just as Facebook and Google have.)
When you decentralize, where providers are only responsible for a relative handful of the overall userbase, 'hoovering' is much more difficult.
I already know about its centralization and being in the US. So what? I don't put sensitive information into Twitter like I do in Google services.
Do you expect your blogging service to be encrypted and private too? I guess the private messages should be secure but oh well, I've even heard Twitter demanding warrants for giving out DM info.
Edit: I do wish we could expect "private messages" to be private.
Maybe I'm lost on the service, but why would anyone expect privacy from Twitter? After all, any company can open their wallets and get the firehose from Twitter in realtime. Why would the NSA be barred from that?
