This is an interesting point because Bret was twice in his life at the point to retain his reputation. In 1997 he received "you sold out" chants from Canadian fans at WWE shows so he had to make something to overshadow the fact that he left for the big money and make the fans feel sorry for him and after he did it he had to retain his reputation one more time by not revealing it was a work to not look like a liar.-Bret has a reputation to retain. If it was a work he would have basically been lying to the fans all this time. The only way I see Bret revealing it was a work (if it was a work) would be on his death bed/in his will
Although I don't know if most fans would even care anymore in 2019 if someone is gonna expose the events surrounding the Montreal, nobody is gonna gain anything from it, like when Dave Hester who left the TV show Storage Wars and exposed it as fake, it was too late and it didn't harm the show, Hester gained nothing with that move and made him only look like a jackass.
Even when Bret returned and feuded with Vince, most fans didn't care so much that the Screwjob story is gonna come to an end, they were just happy to see Bret again in WWE and that was almost 10 years ago.
The problem is that you and many fans who believe and claim Screwjob was real doesn't think that if for some reason the Screwjob was a work there would be no reason to explain anything. If it was a storyline then nobody got screwed for real, nobody was killed or injured so Bret, HBK, Hebner, Vince would have no reason to explain anything because nothing bad happened to anybody, actually the opposite.You're willfully dismissing two verifiable sources of information and refuse to admit they're telling the truth. Bret has been out of the business for eighteen years and each and every time he has remained steadfast in his position that it was a shoot, not a work. He would have no reason, at this stage in his life, to continue to keep this charade up.
Jim Cornette has also said repeatedly he believes the Screwjob was legit in interviews. He longer works in WWE and has been out of the business for well over a decade. Cornette often times goes into specific detail about the behind-the-scenes politicking (i.e. Shawn Michaels behavior) which went on when he used to work in the WWE in the mid 90's. He talks about various performers attitudes, whether they were a prick or not. That does not constitute respect for kayfabe.
Listening to some comments (not yours, I mean in general, all these years) you would think Bret had a contract with WWE until 2002, got screwed in 1997 and then in protest he left the company CM Punk style, then Bischoff heard Bret was without a job and hired him when in reality nothing bad happened and it was a win situation for everybody and it was known where Bret would end up at the end of the year.
