They are being honest, you're just being pedantic. The fact that everyone pays taxes which ultimately pay for e.g. socialized health care/insurance or college-level education doesn't alter the fact that for the person receiving it, said good comes with no invoice, which is a conventional meaning of "free".
The fact that paying taxes is required of all members of the community that organizes, collects and distributes resources in this way doesn't change the relationship between the person and the service at the point of service.

That’s irrelevant to the point the grandparent comment was making, which is that these resources don’t just fall out of the sky and that “I got it for free and I liked getting it for free,” isn’t a good basis for policy.
