My issue is not with the individual operator's right to make a decision. It's with some external person or group being able to impose *their* decision on *my* property as an operator.

For instance, I'm all for banning bots. Mass-distribution of spam is not (imo) freedom of speech because it's not one human person typing out their thoughts into a note. Mass spamming should be stopped imo, though I'm also in favor of relay operators who disagree having the right to allow all the spam into their databases if they choose.

The important distinction here is simple: only the property owner has the right to choose who can occupy their property. The coffee shop owner has the right to allow the screaming idiot in their shop if they choose, but they also must be willing to face the consequences of allowing it (lost business). But no external party should be able to tell the coffee shop owner what behavior they can and cannot allow. Let the market decide.
