There's a lot more than 1 or 2. I can think of a half dozen off the top of my head: Task Force Spectre, Jupiter Force, Access Denied, Proteus, Federation DeepSpace Operations, Section 31, etc. Admittedly, all of them are mega-fleets.
I'm just curious why DStahl said these changes to reduce dilithium price were in-game when that was definitely not the case -- all dilithium costs for projects at all tiers are exactly the same as before Season 7. I assume good faith and that he simply mistyped about it having already happened or was unaware it is not on Holodeck (or even Tribble).
