            What makes you say that? The LICENSE file in the tarball says
            "All the components other than Kaspersky AV are distributed under the GPL."
            All the scripts have the customary GPL boilerplate at their heads. I'm
            not sure what you want.

            Deceptive License Designation - FOR PROFIT SERVICE
            This is not GPL software. This is a service that uses GPL software (pimpin' Kaspersky Antivirus too) and charges an annual service fee.

            The proper License designation should be "Other/Proprietary License with Source" at best. I could find no mention of the GPL in relation to OpenProtect (sic.) code on the website. Other than that it looks like a good idea.

            So sorry, So sad.
