Then they’re offering something else, or you’re going for a reason other than logic. If there are other suppliers offering the same thing for the same price, with no difference in product or experience, you must be going to the same supplier for another reason. Easier, closer, friendlier more trustworthy, whatever.

These are all valid reasons to keep going to an old supplier, but when the legal shit starts providing the same or better experience, more and more people go away from the illegal sources. As that happens, illegal sources start to lose profit and no longer remain viable, they reduce in number.
