Why not?
If somebody was doing insider trading with some shares does it mean those companies should go bankrupt or are bad investments?
Besides, everyone knew that all those auctions were rigged, this is just a guy who took advantage of the system but the system was bad in the first place, the moment a selection on what is to be promoted and what not happen of course it's not going to be anything fair in it.
The danger to NFTs is time, just like with every fad, not some guy making a few thousand dollars in a billion market.
Well, the difference between the share analogy and this situation is that you don't see the actual stock exchange buying shares.
Even if time would eventually kill it, this piece of news may knock off customer confidence in NFTs.
If it ain't dead now, it is dead later.
