I wouldn't say that
I wouldn't say that dieselgate soured people against Bugatti building wasteful cars. Most people do not even know that VW owns Bugatti. And there is a big difference in lying about building thousands of over polluting cars, as opposed to building a tiny number of super expensive hypercars. Now I do think that building a 1500HP SUV is the definition of excess, but they will be so rare that it's better to see cars like this as being art, rather than having any ideas of social acceptance for such a rare monster.
