When you are using your devices you don't know that you are using solutions designed by VHC. Only thing that a consumer can do is buy some security software by a company like Symantec. When you buy a phone you don't know who made the components in the phone. Most investors will learn about VHC when we win in court. Then there will be headlines that big companies have to pay for using VHC products.
Would some buyers want to keep VHC a secret while they are buying all the shares that they want to buy. Big companies control the media and if they want to buy VHC then they don't want retail buyers to buy and drive the share price up. They may not want people to know about VHC.
