You had a chance (and actually still have) for longer lifecycle of server with healthy monetization and a decent communty population.
Moreover, it does not even require a tons of resources: adding some really nice skins to the shop (not those ugly cringy casual ones you keep adding every week) and a bit better DDOS protection/server (that's not expensive, c'mon...).
Poor feedback from the team, all comunity managers are gone immediately after the lauch, critical technical issues, extremely poor marketing decisions.
This literally looks like killing the game on the purpose 
The best thing we can do as the customers: just not paying anymore.
