I don't think that's what 'jacquesm is talking about. It's not about the technical term that can communicate a lot of meaning in few characters. It's about constant use of obscure technical phrases that communicate the same or less than a plain-language description, except you have to work to decipher it. It's obfuscation, in a sense similar to what a JS obfuscator does to readable code.
While I fully agree that ability to communicate science to the general public is incredibly important, the thesis is not necessary the place for this. Plenty of other places are (blogs, twitter, etc) and this ability is crucial for a publicly funded scientist. General large conferences that I am aware of often encourage non-technical translations of abstracts.
