Review-bombing on this scale only happens to games that displease their actual audience. Leaks for The Last of Us Part II have been floating around for about a month and many fans of the first game didn't like what they saw and read. Physical copies of the game have been available since three days before official release date, so it's very much possible that fans who got an early copy had completed the game by the time user scores went live on Metacritic. The hate for this game isn't coming exclusively from people who didn't play it and have no intention of not playing it.
Review-bombing is not going to destroy the game or harm Naughty Dog. All the actual damage, if any, that can result for Naughty Dog will have been done by Naughty Dog themselves.
Your comment that fans of other console brands should be allies with PS fans rings hollow. After all, it is PS fans who find themselves in conflict with other camps all the time because they go out of their way to bash other gaming platforms while the other camps have nowhere near the same level of tension between them. That's why despite no buddy-buddy feelings between Nintendo, Xbox and PC gamers, it's very commonly perceived by PS fans that everyone else is teaming up against them.
Yeah review bombing can ofcourse be seen as an ultimate product of the direction Naughty Dog took with this game but still do not support review bombing OR fake PR marketing scores,review bombing can even be the lesser problem cause we can assume that would be more easier solved than certain company's putting pressure on early reviewers.
Bolded:So yeah i agree with most of your comment except this part,at a certain degree you can just switch all the brands and make that assumption about all of them.It could be more likely that the biggest playerbase has the most amount of that kind of players but even that is an assumption because there are too many factors playing a role here to really be sure and how people feel about it comes mostly down to personal experience and perception.
