AFAIK Reflector's been that way since before Red Gate got it.

In previous versions, I was stuck by how terribly Red Gate implemented the "time bomb". You run Reflector one day and an innocuous dialog comes up saying "A new version of Reflector is available. Do you want to upgrade? OK/Cancel" And if you click "Cancel", it exits, while silently deleting the executable from the disk.

I can't think of another program that violates user expectation quite so thoroughly.

If they are also written in .NET wouldn't patching the timebomb be more than easy: first you decompile the Reflector...

I tried that once; it's obfuscated.
