I too have long had the habit of recommending to people that they remove Norton's products from their machines, and this latest venture of theirs only convinces me even more that I was right to do so.
Avast are another company whose products I recommend people to uninstall, but nor for as long. Until fairly recently they weren't as resource hogging, and as unreliable as they now appear to be, and you can only assume that it's the fact that they're now owned by the same people as Norton, and that it is that which has caused this deterioration.
As has been said already by others, as it is legal, offering people the option to Crypto Mine, though wasteful of power, and to my mind of no real value to the world, is not a problem, so long as the installation and running of the mining software is 100% user's choice, which in the case of both Norton and Avast it is not.
In any case, the full ramifications of running such software should be explained in detail, so that users make their decisions based on fact, and not the fiction that they're currently being fed.
