I expect that a 'internet czar' would be spending much more time trying to figure out how to implement the massive increase in size and scope of the three letter government agencies' ability to 'wiretap' internet activity without warrants.
Which is something that the Obama administration has been pushing very hard for in the past few months. Generally speaking 'Czars' are there to carry out the policy of the administration, of which, reducing the security of our communications is a high priority.
Worrying about discrediting some notion of some private sector security researcher is probably not going to be a high on the list of things they are going to care about.
