The video explains it all

DEMO Mode doesn't work on 1.3-1.5.2
Instead, it defaults to the full version of Minecraft.

Steps to reproduce

To replicate:

1. Get a Microsoft account without Minecraft
2. Log into MultiMC
3. Run a Minecraft Version between 1.3 and 1.5.2
4. Demo Mode does not function, now you're playing full Minecraft

Oh nooo, poor microsoft will suffer from someone downloading a decade old version of minecraft so much.

Interesting development,
Demo Mode WORKS on snapshots 13w16a and 13w16b. This is notable because these snapshots appear to be BEFORE 1.5.2 released which has a broken demo mode. Meanwhile, 1.5.1 has a broken demo mode. (I confirmed all of these)

So these two versions sandwiched between 1.5.1 and 1.5.2 both have demo mode working while 1.5.1 and 1.5.2 THEMSELVES have demo mode not working.

I thought that demo mode would just start working on a snapshot and then we could see exactly which change demo mode fixed itself, but no. It seems more complicated than that.

disregard last comment, it appears the snapshots were in the wrong order according to the wiki
