I found that some environments foster the atmosphere of terror where any person voicing any concern is a threat to others and especially to the person that is responsible for the component being criticized. This is of course completely wrong approach, if people are not free to voice concernes the problems will not be detected and corrected. Over time this inevitably leads to the kind of problems that you have experienced. It is probably good idea to observe and try to understand before you start really interacting within your new environment. It is easy to break some unwritten rule and each company and team has its own, sometimes very surprising ones. In your situation I would probably observe for a bit and note without voicing any concernes. As soon as you start being critical you run the risk of people stopping being honest with you (if they ever were) which will greatly impede your chances of achieving any success. I would try to earn their trust by helping instead of criticizing noticing that in this particular environment, criticizing is not a tactic that will get you anywhere. Help them, let them take some credit. This is probably the best way to make some trust credit which you will need later. Do not criticize ANYTHING unless you are prepared to fix it, yourself. Always highlight there is a difference between bitching and constructive criticism. Under no circumstance direct your criticism at people. They are already feeling unsafe. This is the surest way to make enemies. Do try to talk to them to figure out a way out of the problems but always 1:1.
