I am always surprised at how much hate and disdain I feel when I tell people I enjoy Comic Sans MS. This comes both from people who type a lot, and from those who don't type at all. Somehow, it's become "cool", or maybe even the "default", to hate on Comic Sans MS.
1) Battle royales suck. The entire genre. I grew up on arena shooters - your Quakes, your Unreal Tournaments, and so on. Getting booted all the way back out to the lobby to go through deployment again because of a single death isn't fun. It's making me replay the most boring aspect of the game. Call me when there's a popular one of these which has multiple lives or some other mechanic that ensures a single mistake doesn't result in ~5 minutes of being unable to play the game. I don't have the time or the patience for this.
2) Fortnite's success killed two games I was really interested in - Paragon, a gorgeous third person MOBA, and a reboot of Unreal Tournament.
Those first two are very concrete and have nothing to do with tribalism. The last one is a bit murkier:
2.5) Fortnite seems to be aggressively marketed towards children, which means its players are probably disproportionately children. Minecraft had this problem too, but it had a single player mode and private servers which allowed you to sidestep it.
That one probably carries the whiff of "kids these days", but when you consider that the game is going to be designed to cater to the average player...
Fortnite has numerous other game modes than solo BR where this would be the case. At it's most basic level you can play duos, trios or squads where you are "knocked" but can be revived by a teammate, or "rebooted" if you get knocked and eliminated. There are even more varied game modes that are even more arena-like: 50v50s where you immediately respawn with the same loot for example. I have no stats but I'd guess that these alternate modes are more popular than the main BR modes.

Cute, but seems more like a gimmick you might see on a dead Quake server than something you can base a game around.
I love weird gimmicky indie games, so I thought I'd love Cult of the Wind, but...there really wasn't much there. And I realized an ultra-niche single-player game can find cult success, but an ultra-niche multiplayer-only game will probably never have enough people online at once to keep going, and sink without a ripple.
But people keep making them, so some of them must be succeeding, right?
(I'd like to point out that you can setup games with your friends where you don't get booted out for dying.)
It was fun until you hit what felt like a brick wall in progression. If I recall it got super grindy really quick. People hated it but the company got lucky by saving it by adding BR mode. Things quickly started to become free and the game is a completely different game than what I bought.
For me it's not that I hate people that play it. It's sort of like waiting in a long line to go to an amusement park you've been dying to go to. You pay to get in and it's terrible. Then they immediately open the gates and let everyone for free and change it to a water park. I'm just annoyed by the entire experience.
For when I want a long term profile, weapons that carry over between raids etc, then I'd invest that time into an RPG.
edit: it's worth adding that I have no issue with unique avatars in FPS. I just don't think it's fair being spawned 5 meters from someone with a customised minigun when the best pick up you can get on that level is a handgun.
There is no such thing in Fortnite.
I don't like fortnite at all though, everything feels exceptionally random (bullet spread, damage, weapons, kill zone, you name it, it's got a couple RNG calls), the build mechanic feels more like a crutch for not knowing how to play around cover unless you really put effort into learning it, and even then it's basically "build 3 walls quickly" or "destroy a wall to shoot through it" type "skill".
It just never grabbed me, I played a few casual rounds and did reasonably well (top 5-10 twice in my first 5 games, with a few kills at least on average, no wins or top 3s though) but it felt like I got lucky, either catching enemies out and getting their good guns, or killing people who could barely aim, then dying to someone sitting in a shelter on a cliff with a one-shot kill sniper that they picked up at the beginning of the game.
If I want the BR experience I'll play Apex, if I want a wacky kids game where you can only "heavily influence" what essentially feels like a ball of randomness, I'll play Mario Party.
I'm not sure it's tribalism that causes folks to respond this way, per se, but it has some elements of it. I suspect all hobbies and pursuits in life deal with such negative reactions - it's certainly a thing in all the hobbies I've had. (Who knew model railroading was such a warzone?)
Best thing a person can do is shrug and move on from the haters. Be glad you found something you enjoy that doesn't involve tearing other people down.
