Not my first time seeing ppl getting kicked off platforms. Probably it has nothing to do with your game at all. Sometimes user's attitude pissed off the entire company. As a bird of the same feather, being right and on-point on the double-standards did not appeal to the platform owner, especially I exposed him in public MULTIPLE TIMES; instead, being too accurate and an advocate who ceaselessly opens fire and criticizes a platform for its lack of management and morally controversial policies every single week, I got the kick too. That's my story short.
So, ask not what you can do for the market/ppl, ask what you did to the platform owner and its workers. Obviously I was helping them in my case, but adding tons of workloads, haha, yeah, one of the mods who works for them leaked me the tip, now I see things VERY DIFFERENTLY.
In your case, your product got removed. So, maybe use a different one like GoG? To be frank, of all those game selling platforms, GoG is probably the last one that isn't aiming to profit from gamers and developers, as a developer yourself, why not join the good side that has your back? Why would you want to join the evil forces of Steam if they choose to compel you out of their place like an exorcist?
(Just in case, have you pissed off anyone lately? Could be someone telling them about your game, if they are genuinely targeting your game only. I have seen shit like that before...)
Just a passerby seeing your rapidfire profile responses and decided to get into THE RABBIT HOLE. Oh boy, I am digging a grave for myself XD
