I clicked on the download and was directed to Fengtao's site. For fun I clicked on StormPay and got following warning:

INVALID/IMPROPER use of the (GLC) Link Codes. Insufficient or improper parameters specified! Please check with your Site Administrator.

PLEASE NOTE: You may also get the above error message, if (1) the "Merchant" is using an INVALID PAYEE EMAIL, OR (2) the "Merchant" is using a website that is attempting to have you log in to StormPay within their OWN browser window/frame. For your protection, we only allow Users to log in to StormPay withtin a "fresh" browser window. Hence, we strongly advise that at ALL times when you log in to StormPay, please ensure that https://www.stormpay.com/ is at the BEGINNING of the URL shown in the browser ADDRESS window. ALSO, you must ensure that the Secure Lock icon is in the status bar of that SAME browser window. If you ignore this advice you may be putting yourself at risk of having you account PASSWORD stolen.

Based on that I believe they have been spoofed as I have been to that page and did not see anything about selling Fengtao's products. I will email him and ask as I was planning on sending him a donation because his product is a good learning tool for terms that I do not yet understand.
