Sorry, you're just rationalising what you do with a security argument. If it
were true then the FSF would accept running non-free Java 1.4 applets
providing the security manager was configured to disallow network etc access.
There are no differences in the theoretical abstractions of the two
propositions.
Of course rationalising things away and even having cognitive dissonances is
something everybody does including myself. If acting on sound rational
information and advice was natural for humans then there'd be no obesity
epidemic in the West, most would take enough exercise, the tobacco companies
wouldn't make much money etc. etc.
So I'll just urge you to maximise your software freedom and consider what the
next small step in doing that is.
