That "someone" is doing far more harm than he realize. His refusal to use any syndication system but twitter is akin to a refusal to use any text messaging system but Facebook. (There is RSS on the one hand, and SMTP/XMPP on the other.) People like this are powerful contributors to the network effect favourable to proprietary services like Twitter and Facebook. I know that true freedom is not easy (Postfix configuration through SSH is not for my mom). But one can at least use proprietary providers of open protocols.
