Bundesrecht Art. 28g:
1 Any person whose personality rights are directly affected by a representation of events in periodically appearing media, especially the press, radio or television, shall have a right of reply.
2 There is no right of reply in respect of accurate reports of the public dealings of an authority in which the affected person took part.
I'm not an expert on Swiss law, but I don't see any reason that they'd be entitled to a reply...? Let's hope the courts see it the same way. Bullying small independent media for their factual reporting is just low.
Wtf, isn't it just pressing a button...? Though I guess you avoid the risk of people forgetting.
It's also required in Sweden, but the building owner is responsible for installation, whereas the people living there are responsible for testing that it still works.
