I also don't see them as supervillains and understand the whys behind it. But, like Mongrolian said, you seem to understand the word 'professional' solely on the meaning of someone capable of doing a specific job while the word imply much more. As quoted from wikipedia:
Due to the personal and confidential nature of many professional services, and thus the necessity to place a great deal of trust in them, most professionals are subject to strict codes of conduct enshrining rigorous ethical and moral obligations.
Thus, calling them unprofessionals for the lack of ethical and moral on their recent actions is quite justified. Again... I don't condemn their decisions, but how they handled the situation.
