No. The public official can still mute them so they don't see they. The public official doesn't have to interact. But they cannot keep someone from accessing their feed when they use it for politics. They still have the right to access the information directly. These same people can right letters, after all. The politician doesn't have to read these letters nor respond to them. But in doing so, they can't keep people from sending letters nor stop them from getting information about the office. In short: When they use their tech for political motives, the politician's want to block people doesn't overturn the people's right to get information from the source, be it twitter or a press release on the government's website.
