What are their motives could it be that they are just anti Bitcoin or attacking Bitcoin because it is a competitor that will soon push them out of business.
Some of these business owners are into thinking that Bitcoin is competing against them like if you are in the banking business, money transfers, that is absolutely what they might see. I know they have some reason as people who are in using Bitcoin can no longer use their services and that much more if all establishments are accepting cryptocurrencies already. They don't want to file bankruptcy and so they protect their reputation as well.
Well, I can't blame them either, but that is how the development goes, sometimes there is someone who feel bitter and get hurt.
