When Odyssey launched you had exactly that with footfall tags. And yes, some people were upset about that too, for the same reasons.You are just arguing in bad faith out of stubbornness. I think you understand perfectly well what the argument is, so there's no need to continue feeding you any more.
However, what I wrote earlier gave me an idea:
There's another thing in the game that's a one-off thing: First player to get it gets it forever, and nobody can get it anymore, and it's gone. And it's actually very similar to system colonization, and I'm of course talking about first discovery, first mapping, and first footfall.
However, there's a crucial difference: You don't need to be in the game exactly on Thursday at the exact time that the servers come back up in order to get first discovery on a system. You can do it whenever. Sure, it's still a very first-come-first-served system, but it's not tied to a particular day of the week and, especially, at a particular time of day (which in itself is quite random, and may vary by literally hours, which means you would need to be sitting at the launcher potentially for an hour or two in order to log in as soon as possible after the maintenance break).
What if system colonization worked in the same way? Rather than being tied to the Thursday refresh, it's available immediately when you complete your previously claimed system: Once the completion threshold has been reached, you could immediately claim the next system, rather than having to wait for Thursday.
This would still have an element of "who gets there first", but at least it wouldn't be as tied to a particular time of day, and thus it's less unfair to those who literally cannot play the game at that particular hour. Now it would be more of a question of who can build the fastest, rather than who is able to play the game at a particular moment of the week.
It is what it is, I suppose. If you have a specific system in mind it might end up in disappointment, and I can see how that is upsetting to people.
