I generally avoid talking too much with my managers. I usually do without asking what I think is right without getting permission (better ask for forgiveness later which rarely happens). When asked I will tell them what's going on but without asking I am quiet and do my job. When my team has to work with other teams I also talk to them directly without manager if possible. This works well for me.

Other people have the opposite approach always talking to their manager and trying to develop a relationship. From what I see this only works for some. In the end they want somebody who does the necessary work and causes the manager as little work as possible. It's pretty rare that a manager actually mentors people to get better.

As far as asked not to give talks it seems pretty clear that your manager doesn't have your best interest at heart.
