That's something people are responsible for themselves, because that's what they sign up for. It's pretty silly to invest in cloud mining, which directly means that you agree to all their terms, and then later complain about something that you could have figured out before investing already. Mining in general involves so many variables, that it isn't interesting to jump in, unless you are accepting all its negative aspects. Even if they increase their fees with 50%, you have to swallow it. Obviously, they won't just rush in and set these level of fees instantly, but they slowly distribute it in a manner you will still be paying it, but feel less angry about it because it doesn't look like much of a change. It's a solid scheme structure that always favors the house.
