I was fired from my job yesterday after giving my two weeks notice a few days ago for a better job, are companies this petty?

I understand companies can do what they want. But working for this company I felt unappreciated, rarely thanked for my hard work, they pin pointed stupid things on me, just a toxic work environment overall. Came to work on time, did my job and went home, what more can someone ask for. I told them I found a new job a few days ago. The president of the company tells me, you know how much money we invested in you. I was doing this job for one thing — make money and leave. Companies don’t give a heads up if they lay people off. I swear the hypocrisy of employers, glad I left that place and have another opportunity with more growth.
