This has been my issue with the ending since it aired: The obvious implication that Tony was murdered has no narrative underpinning whatsoever.
There was no shown simmering dissent among Tony's crew during the ongoing war with New York, as to a man the family was ready to do battle (unlike a few seasons prior, when high ranking capos were openly questioning Tony's decision-making regarding protecting the whereabouts of Tony B from New York, and all-out conflict had yet to start). Any wishful thinking about the motives of Paulie and Patsy is just that. Paulie Walnuts was shown only to be an unwitting traitor to the family, an issue he quickly rectified, and Patsy is shown in the final episodes being over the moon to get closer to Tony via his son and Meado.
The war with New York was shown to come to a conclusive end, with Phil's highest ranking confidant (and underboss of the NY family) negotiating peace with Tony while Phil was on the run. Could this peace-making merely have been a ploy to bring Tony out of hiding to make a hit easier for NY, breaking a code of honor that the members love to pretend to adhere to, or could Members Only Guy be a member of a faction still loyal to Phil who didn't feel bound by the truce? Sure, but that kind of narrative thread was never developed in the final season, with the closest instance of the show even mentioning reneging on a newly-formed peace being when Christopher went to go bury Tony B up in Kinderhook, and Tony S said "It may be over, but watch your back."
There's little question that Tony was killed, and that MOG was the shooter, but the entire narrative premise of the murder is not supported by anything shown to the viewer by the show's "Ren". It seems that the show enjoys a bit of shielding from criticism for open-ended or outright hole-riddled plotlines by sometimes claiming vagueness for the sake of adhering to reality (Did the Russian die in the woods? Was Christopher visited by the ghost of Mikey Palmice in purgatory? Who can say, really?) and other times claiming the world the show inhabits contains the supernatural, which explains things like Paulie seeing the Virgin Mary, Paulie's psychic being able to name a murder victim of his (no way a cold-read is that specific), Tony divining that Pussy was a rat in a fever dream, etc.
I just think that, after making the show a mega-hit for 6 seasons, Chase's forays into funky and psychedelic storytelling in what was originally a straight mob drama, as well as with all the extended production delays in later seasons due to contract disputes and the like, fans deserved to be at least told what happens to Tony, not left to their own devices to pick and pull at previous plot themes to justify an ending that was implied. And yeah, I know the thinking was that maybe a movie could be done after the series wrapped up, but if Chase is such a good writer that we get to admire his hours-long attempts at writing about dream states, he certainly could have figured out how to bring about a satisfying, and explicit, narrative conclusion to the series while leaving enough meat on the bone for a movie afterwards.
The war didn’t end - it was a temporary truce.
Remember you don’t kill wife kids or whack someone in front of their wife / kids.
Tony whacked Phil in front of his wife and grandkids so Tony had to be dealt with the same. And they did that by killing him in front of his wife and kids. Eye for an eye.
