The only thing that matters is how much programming efforts and financial support a vendor puts in an AV. It doesn't matter whether the financial support comes from users directly
(as in paid AV) or from users indirectly
(as in CIS users doing online business with companies buying certificates from Comodo).
Such claims from Symantec is, in my opinion, nothing but a sad joke. They clearly don't understand that there are other possible business models, or - maybe more likely - they are desperate to fight competitors like Comodo, who takes market shares from Symantec.
Melih, gradually and eventually (although you have already come far) you will prove Symantec to be wrong.
