That distinction is horsecrap. A hotel manager can be forced to offer their wedding package for a gay wedding and a chef can be forced to cook for a gay wedding because they run venues that have been declared "nonexpressive" by 6 people who don't know the first thing about those professions. But a website designer cannot be forced to sell websites while running a website shop.
They don't believe in that distinction. They're just taking a step towards outright illegalizing queerness. They'll tear down that separation as soon as doing so can result in more discrimination.
