You misunderstand the purpose - it's not intentional obfuscation. Its the lingua franca of the field. A technical term can define in one phrase an entire concept that would be tedious to spell out each and every time. It can define one 'chunk' that you can then combine with other chunks to develop deeper understanding. Surely you can agree with that?

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.

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.
