Why did Wikipedia change its export function so it no longer works with any other wikis?
Earlier this year Wikipedia changed Special:Export, so that everything exported is in a different format than the one it had previously used for years. This means that other wikis, such as wikia, can no longer import pages. Was that done on purpose? Dream Focus 22:17, 30 April 2012 (UTC)
You will probably get a quicker answer at WP:VPT where the techie types hang out.--ukexpat (talk) 02:30, 1 May 2012 (UTC) I'm afraid I don't know anything about it.--Jimbo Wales (talk) 09:46, 1 May 2012 (UTC)

This is subtle, but a huge nail in the coffin of the interwiki collaboration idea.
For a decade, the writers of Wikipedia assumed that if there was ever a reason to, they could easily take their content elsewhere.
Now database dumps don't work and Special:Export doesn't work.
The WMF has completely broken the trust of the original user base.
New license, new terms of use, and two key features of the wiki are disabled.
