[clamav-users] GPL license question

[Borough Rumford]

Hello,

I know clamav is released under GPL license, and third-party commercial app shouldn’t link libclamav.

However I find there is one anti-virus app link libclamav directly and is published on Mac app store.

This app is

https://itunes.apple.com/us/app/bitmedic-antivirus-malware/id1001746820?mt=12

Below is otool result of BitMedic binary 
otool -L BitMedic 

BitMedic:

/System/Library/Frameworks/SystemConfiguration.framework/Versions/A/SystemConfiguration (compatibility version 1.0.0, current version 699.1.5)



I want to know if the way used by Bitmedic is legal and other developers can also use clamav directly in their commercial app.
