Does anybody know why Randall Munroe (XKCD) has made a mockery of RSS on his site? I thought his joke was funny at first, but he has left it there and now the RSS feed from his site is worse than useless. Here's the content I get from his RSS feed on both my Android phone and my iPad:

"xkcd.com is best viewed with Netscape Navigator 4.0 or below on a Pentium 3±1 emulated in Javascript on an Apple IIGS at a screen resolution of 1024x1. Please enable your ad blockers, disable high-heat drying, and remove your device from Airplane Mode and set it to Boat Mode. For security reasons, please leave caps lock on while browsing."

This behavior began several months ago. Previously I could access his content on the same devices.
