Why is this a scam? Because they aren't holding your hand through the whole process? They aren't advertising to be your "development team". If you can't start the genesis block of your own coin should you even deserve to create it?
They deliver their advertised product, albeit it's hastily done in 30 min or so. That gives you a copied Bitcoin 0.8.6 client (which you can download for free from GitHub). A new logo pasted on the GUI (which you could swap out in less than 1 min in your directory). And they change a handful of key parameters in a couple source files that you could also change in 5-10 minutes if you know how to type in a search bar.
All that is clearly visible on their site. Your laziness combined with their simple copy-paste products doesn't = scam. It equates to you being lazy and paying someone else to copy and paste files for you at a rate of $400/hr. Great business sense on their end if you ask me.
Get over it and learn something about your new coin "you created". Hint: start with a search on "generating the genesis block"
A scam is something that people think are buying and not receiving. Sure it was naive from all of us, but I think we all searched on coingen and Matt before buying ... being confident enough to send some BTC his way, hoping for a minimal instruction. The biggest part of the scam is his silence towards all his clients. Depending on wich part of the world you live, everything comes with a warranty of somekind.
How long would it have taken him to write a short post or tutorial on how to use this product ? He own everybody a minimal respect. We trusted him enough to buy his product, he should show a little be a respect towards us.
