Is it acceptable to use proprietary software (platforms) to promote software freedom?

[Adonay Felipe Nogueira]

Problem is: The freedoms of the software are prerequise for security.

This is problematic in Tails case because it has non-free parts inside a
product that is provided by a project with goals to provide security and
privacy.
