This is the last post I will write on the subject because this dispute does not involve me. The only reason I'm writing this is because I have been a modder since 2019, seen drama play out badly before, and would sincerely like to preserve the positive vibes in the Factorio community.
I found the other thread and the response: https://mods.factorio.com/mod/pelagos/discussion/695a21b4d575086cee24496e My initial take was entirely accurate. Talandar is very clear about why they put the blacklist in place. Xorimuth and I maintaining Cargo Ships intentionally make it as unrestrictive as possible, but there are other valid ways to design a mod. Talandar has every right to maintain their artistic vision for the planet they created. Continuing to complain about it will do no good for anyone, and you need to accept that.
There are lots of things you CAN do without complaining:
1. Fork your tweaks mod with a new name and without the changes to Pelagos. Accept that Talandar's artistic vision is entirely consistent with how Space Age is designed, where each planet has an arbitrary specialty forcing you to visit it. If you want lots of random planets with no real purpose, use Space Exploration instead (I'm only half joking).
2. Fork your tweaks mod and don't upload it to the mod portal. You can distribute it to your players outside the mod portal, that way it's not publicly visible.
3. Fork your tweaks mod and upload it as an "internal" mod so it is not visible in search. If you had done this to begin with, it's possible Talandar might not have cared.
4. Instruct your players to modify Pelagos' info.json after they download it. People have done this to Space Exploration for years because Earendel insists on blacklisting teleportation and infinite resource mods.
5. Remove Pelagos from your server and wait for Talandar to release the gameplay mechanic mods separately.
6. Make your own mod for a new, different water planet that does not add restrictions that you don't like. It's not that hard.
7. Technically, you always have the nuclear option: fork Pelagos itself under GPLv3, if you are an immature person and want to make that very clear to everyone on the mod portal. Not only will it make Talandar more angry, it will confuse users and result in bug reports being posted to the wrong mod. Please don't do this.
If you ask me, 5 is the simplest option, and 6 would be the most fun. That's all I have to say.
