Pretty high. Given they are being punished for a business decision. They often go on about being punished for political action but this is a clearer example of what I generally think is pointed to. They did something they did not politically agree with and they are economically punished for it.
A joke really. Also, if companies are allowed varying degrees of speech than one could argue they are violating their rights. As stupid as I think that is, we could be on that route anyway.
I would argue it is 7+ though, probably more towards 9 in my book if there was such a scale.
I always had an issue with the NRA ID counting in some states for voter registration etc. and other places.
The irony is that the tax break is, in a sense, already government interference - overtly favoring one company over others. So if they had gotten rid of the break for other reasons, I would have been in favor of it. But yes, as you said, they had a clear purpose of punishing a company for a business decision they didn't like.
