If you don't like the game, don't play it. It's 2019 and browser games are not as popular as before and that won't change. People today will invest their time in PUBG, WoW, LoL, Dota, and many other games. Games like this are a dying breed, nothing we can do about it.
Saying that the GF doesn't care is not helping, this game is not their "primary" focus. They have other games that make a lot of money so the invest their resources in them, not Gladiatus. It's very simple, they are a company and every company need revenue to survive, if a project doesn't make money, drop it and try something else. That is how the world works.
The reason they didn't shut Gladiatus down is because it's cheap to upkeep. And in my opinion (What I personally think) the game has never been better, so many event, new things added to the game, so much stuff to do and things to experiment with.
Bottom line, if you don't like it move on.
