“Easy installation” with two screws seems like a benefit to customers except when they come back to their parked bike only to find their expensive mod also had a hidden feature: “easy uninstallation”.
You won't be able to remove the cassette and crankset with a multitool but a full campagolo super record EPS groupset MSRP is above $4000.

From a cyclist’s perspective, this is fundamentally a stopgap product for “curious” customers dipping their toes into e-bikes. I don’t say that necessarily to criticize it. There’s a place for a product that someone can put on any old bike and see if they want to buy a more expensive long-term solution. But that doesn’t make it a product I’d recommend.
The tire wear problem is significant enough that there are heat resistant tires specifically for this type of drum application (designed for old-style indoor trainers, not for use on the road), because use on a drum will cause premature wear for normal road tires.
1. someone has a cheap disc brake bike for pleasure rides (mostly in the sun)
2. they get something like this for commuting or whatever
3. now they're on their disc brake bike most days (including when it rains), going faster than they're used to
it's not the end of the world, but it also doesn't seem great
