I did not know that blog post. However, it does not give evidence that Moxie Marlinspike is friendly to federation and third-party clients. If anything, it shows that he opposes open, interoperable protocols as well. Moxie Marlinspike asserts that federation needs standardization and that standardization inhibits changes. He also asserts that protocols have to change to keep up with changing requirements. His unspoken assumption is that it is impossible to create real-world forward-compatible protocols. While I agree with the first assertion, I strongly disagree on the latter two. Consider that protocols and data formats that do not have to change exist. An encoding like UTF-8 will probably never have to change to keep up with new codepoints. Also consider that forward-compatible protocols and data formats exist. HTTP seems to be a very good example for that.
