The fact that the law was passed by the same men who ratified the constitution says a lot about their concept of freedom of speech, even if it was controversial and short lived. If the founders really meant for free speech to be as expansive as it is today it is hard to see how such a law could have been passed in the first place.

You can also argue that it was defeated by the same men who ratified the constitution, and that the "free speech" side ultimately prevailed, therefore they really did mean free speech to be that expansive.
