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

I think you mean "private software" which is only used by yorself, and
not shared to anyone, not even co-workers. Once you share it at least
with someone, it ought to be free/libre because it's no longer

Also, I disagree in the statement that Facebook can simply be considered
only a user of private software, and on the argument that Facebook
doesn't expect the user/visitor/guest to use non-free software. In fact,
Facebook does expect that, see the JavaScript trap, which is
*client-side* software, but provided *by the website*:
