Okay. You’re still doing tech support either way. I have no way of knowing how much free tech support you’re willing to give, hence my caveat of how much you’re willing to support them.

Netflix would disagree. People feel like they’re supposed to be getting access to a service, and if they’re not getting it they’ll complain to the nearest party to what isn’t working. In this case that’s you or Netflix being asked questions about why the router isn’t working.
That it’s wrong or irrational has nothing to do with who’s getting asked the question, and who’s the first line of troubleshooting when the service doesn’t work.

If people didn’t ask the wrong people questions, Netflix wouldn’t need support articles on how to reset your router.
