Sorry, but I don't follow your logic.
You're acting as if a huge number of players are playing in an alliance server, causing regular servers to be full of PvP only players. There's quite literally no evidence to support this idea, and is entirely conjecture. In fact, every normal server I've been on in the last few days has had more players fleeing from me, than there was people who stayed and fought when I engaged them.
Let's say there's an alliance server active right now. At most, that's six galleons, with 24 players in total, at any given time. One full server out of who knows how many regular servers, where players are playing normally.
I'm glad we could partially agree on that at least.
The discord servers themselves have tons of members, but not all of those members are all playing at once. From what I've observed from the one I played in once, they had one server, and a que of people that cycle out. So if I had to guess, and judging from how long some were in que, maybe 200 max per day without even taking into account not always getting a full server, or slow days.
I would, and still vehemently disagree that the already dwindling number of these organized servers has any intrinsic effect on regular servers. Granted, there used to be a lot more active alliance servers, but they take a lot of organization and upkeep to keep them going. Sea of Thieves just recently hit over 20 million players. Now sure, that isn't 20 million online all the time, yet despite that, I still cannot believe that a few straggling alliance servers have any effect on the tons of regular servers.
Now, I know the Microsoft store doesn't project their online numbers, but Steam does, and there's typically anywhere from 40k-65k online players, again without taking into account time of day, day of the week, etc.
Without knowing exactly how many regular servers exist, it would be hard to pinpoint when regular servers would be in jeopardy from alliance servers. However, and in my opinion, there would have to be hundreds of constantly active alliance servers before we would see any sort of absence on base servers.
I'm a bit confused on your second to last sentence. Are you referring to alliances made in normal servers? I'm also not sure where you're getting your "thousands" number from.
The only issue I can even slightly see with the leader boards is people cheesing their actual emissary value. Even then the issue is very minute, considering there is no way to discern whether someone earned their value in regular servers or an alliance server. As for earning the emissary cosmetics, and as I said before, people will earn them gradually, alliance server or not.
I would understand and be upset if players earned emissary value from other crews turn-ins, or if players earned commendation progress from what other crews in the alliance turn in, but neither are the case. You only get emissary value and commendation progress for loot that your own crew turns in.
I've been playing since the beginning, and I'm almost exclusively PvP (save for when I just want a chill session, and I'll sail around and do whatever world event I see, etc) and the entire concept of alliance servers have never bothered me. I always saw it as another medium for people to enjoy the game. Some people love PvP, some love to do PvE, some love both interchangeably. I believe that there are/should be mediums for everyone to enjoy the game, as that is the nature of a sandbox game; player agency.
