[squid-users] GNU GPL Question

Symantec provide a version of Squid to their Symantec.Cloud customers
that they call the "Client Site Proxy". They've modified the source to
add two "encrypted" headers (X-TEACUP and X-SAUCER) to each request,
and only provide a Windows version of the product. These headers
provide reporting information back to the centralised admin portal. I
think one of them contains an encoded username, not sure about the
other.

They're refusing to provide a Linux version on the grounds that their
modifications are "confidential" due to the "encryption" of the
headers.

Seeing as Squid is GNU-GPL licensed and they're providing a commercial
product based upon it, aren't they required by GPL to make the source
code for their modifications to squid-cache available to the consumer?
