I think that also works in the favor of Sci-hub though.
> I regularly receive requests from Sci-Hub users to help them download some paper that cannot be opened through Sci-Hub. The number of such requests increased in the past two years, since Sci-Hub database updates were paused. The opposite also happens: users ask whether they can upload to Sci-Hub some paper that they have bought or downloaded via university subscription.
Now, instead of having to deal with all those requests, Sci-hub can point users to this market to get the paper instead of eating up its limited personal resources. Papers that they can automatically scrape will still be there as always, this is just to handle those special requests that need a human. If the user can't or won't set up a coin then they don't want the paper badly enough. I mean heck they can always go buy it from the journal.
