Sorry but having to share my contact info at a business is a step too far for me, and is a breach of individual liberty that I am not willing to participant in.

Sorry but having to share my contact info at a business is a step too far for me, and is a breach of individual liberty that I am not willing to participant in. Apart from privacy concerns like in the linked article, I think it is also the kind of normalization of authoritarian mechanisms that we just do not need. Some may call this a slippery slope fallacy, but to them I say that slippery slopes / boiling the frog are an effective way to go from a minor breach of liberty to something more dangerous, all with the public's support along the way.
