iNabber wanted to make a silly podcast someday called E-boys. His """friend""" Alex and a few other blokes I forgot the names of made the podcast without iNabber without a reason given. iNabber was pretty upset at first for being betrayed like that without them explaining why he couldn't join the group, yet has since then sort of downplayed the whole thing as being no big deal. While I did consider including this in the OP as another example of Alex's backstabbing, I figured that A. the lack of information and B. the other guys (presumably) being a part of the decision makes it difficult to fully pin the blame on Alex.
Seeing as the E-Boys were brought up I may as well expand a little on who they are as a little primer for people that don't give a flying fuck about bongtube. Will keep it brief to avoid derailing and (imo) none of them are cowish apart from the aforementioned iNabber.
The E-Boys consists of Alex, Memeulous (often just referred to as George), WillNE and James Marriott. They all do similar content to Alex except they don't fling life ruining accusations around freely and are capable of taking the L when wrong. They've been good friends long before the E-Boy shit happened and they generally stay out of drama (James Marriott iirc had a brief run in with... Nikocado Avocado but it was a big ol' nothingburger and isn't worth remembering).
Memeulous and Alex are roommates and are a common target of the weird nsfw ship fantasies from fangirls but it extends to just about any vaguely attractive male Alex has talked to.
And this is just my own autistic speculation, but to add on to cucking iNabber out of the E-Boys all of the guys in the friend circle will occasionally take loan of iNabber's dog, Kenji the Shiba Inu to dogsit him for a few days. Epic meme doge might give them more views/interactions, but even if it doesnt they still got to play with a fluffy fun dog without any of the longterm responsibility.
Basically I'm convinced that the E-Boys only actually hang out with iNabber because of his dog
