If I used this in a commercial product, it would be trivial (absolutely trivial) for the owner of the original product to take me to court for illegal distribution of their copyrighted works, based on the argument that the code I was distributing (for profit!) was written by someone who (by own admission in public) had reverse-engineered the original product.
IANAL but I'd be willing to bet money on this.
The only questions would be (a) is the original product one that matters enough to protect in such a way and (b) does the owner of that original product have the money and lawyers to start such legal actions.
This isn't some random app. This is one of Microsoft's crown jewels we're talking about.

The original Skype code is clearly not available to anyone outside the original Skype team or some team inside Microsoft. What is publicly available is a binary that is produced from this code.
I made a quite clear explanation of the argument a lawyer would use. This open source client is in effect a pirate copy of the closed source client. I expect it will disappear from Github rather soon.
