This page is dedicated to software presented in way that falsely suggests the application in hand have its source code available.
How it works
There can be multiple tricks used for this deception, including:
A website design that draws similarities from an open source developing platforms (e.g. Github star badge).
Public source code consist of compiled binary files.
Why it is a problem
Falsely rendering themselves as transparent and trustworthy which may deceive consumer into less caution while handling the software.
Application can perform unnecessary or malicious commands on host systems.
What doesn't consider as deception
Some close source application use open source platforms(e.g. Github) to publish their program for a reliable or alternative download server.
Examples
