This reads like a case of 'all about me'-ism. It sounds like this person negotiated their salary, and then decided the company didn't value them _because_ the company agreed to raise it when asked. If your goal is to have people throw money at you which you don't ask for, you are going to have a tough time working. A company that's willing to double your salary when you point out the offer is low sounds pretty great to me.
It then sounds like some other timelines were shifted, but rather than engaging with the company to learn what was going on, they silently invented more 'disrespect'.
Building a product is hard. It's also expensive. Many many companies go out of business trying. The company being somewhat reasonable with money, and moving other deadlines around to accomplish their goals, is not evil in and of itself. It sounds like OP needs to learn how to engage constructively, communicate their concerns and questions, and empathize with the people they're working with a bit.
