You are attributing malice to what was an expression of an opinion here. My personal experience is that games like Deadlands, Shadowrun, D&D and even sometimes L5R/Exalted/Vampire are pretty much run and played in almost the same way. Just like games like Brindlewood Bay, The Between and Apocalypse Keys pretty much have the same core play loop. The same could be said for Blades in the Dark, Scum and Villainy and Court of Blades all fundamentally being mostly the same game under the hood in terms of how players and GMs are meant to approach them.
I personally do not view this as the same black mark that you do. I have played, run and enjoyed many of these games. I would personally jump at a chance to play Cyberpunk, Vampire, L5R or Classic Deadlands with any GM I consider a good scenario designer and storyteller (and have done so within the last 3 years). I simply see games that you see as very different as very similar. Feel free to disagree and engage with me (if you want).
