So I decided to write a php script for my server to intercept the HTML emails and convert them to plaintext and deliver it to me, but I ran into a slight problem which has enlightened me as to why the emails are so large, and the real reason plain text emails are no longer available: every single link in the email is a tracking URL instead of a direct link to Wikia.

Here's a sample "Compare changes" button: Compare changes 

"All of the normal links you'd expect are included"

- From the blog post.

Nope. I expect normal human-readable link like http://dev.wikia.com/wiki/WHAM?diff=25864&oldid=25748

I'm sure the information Wikia gets from tracking email clicks will be very informational, and help Wikia improve their services, but I would have a lot more respect for Wikia if they were more upfront about their intentions.
