There are already FOSS replacements for Skype, such as Tox. The fact is that if every line of code can't be inspected then the software can't be considered secure, and we're forced to put blind faith in a faceless corporation, which is understandably not acceptable for many people. I don't really care if you think this is "practical" or not. That's simply the reality of the situation. Proprietary == insecure.
If a company is unable to profit off of making FOSS software then they can go ahead and keep it closed source, but they should not be claiming that their software is secure when their claims cannot be verified. That's simply dishonest, and only proves the critics right about their trustworthiness.
