Sharing arbitrary copyrighted content did not ruin BitTorrent so I don't see why it would ruin this.
And this has a legacy roughly as long as BitTorrent itself. The fact that BT never established a footing in other use cases (even those where you would think it would be a great solution) is telling.
Windows Update also allows the user to opt in to use a non-bittorrent protocol for peer-to-peer delivery of updates to other Windows users. But of course, it's not true Bittorrent.
