Actually most people are wanting to look at the source to evaluate whether or not this is worth investing in.

There have been many scams in altcoins.  So auditing code, is pretty essential, imo. 

The fundamentals of distributed cryptocurrency, and trustless actors (including the original devs), is dependent on open source.  Otherwise you are basically left with a centralized coin, where you need to trust the dev.

Ultimately, nothing wrong with that.. but it is what it is.
