It’s not about trust, of course they don’t deserve trust. It’s about showing them that players have influence when it comes to their bottom line and that they can’t just get away with anything they want to do without it hurting their main objective.
In other words, be nice to the community and they are going to be nice to you. Be shitty to the community and they are going to be so shitty towards you that it hurts your profits. That’s the only motivation that makes them go back on something that they want to do.
If they think that people are going to behave negatively towards them and review bomb their games regardless of how they act, they will just keep acting however they want.
