From what i have gathered, if Segwitx2 activates then the Core Devs will LOOSE a lot of authority/respect and will possibly be overlooked/ignored on future upgrades/updates. Because Bitcoin will exist on this Segwitx2 code... Which is piece of code that has NOT been produced by the core devs. And FYI, the core devs (and satoshi) have been releasing all Bitcoin updates up until this point.
