In terms of potential harm, it's like the difference between a handgun and nuclear bomb.
This offering is a stalker's delight. The only thing that would make it worse is if they paid people to turn up to a specified location and take photos, like some sort of Uber for creeps.
At minimum, they should have a form where you can opt out of having your home included in this sold imagery. Better would be to notify all property owners and dwellers within a photographed region that the imagery has been purchased, with an option to opt-out. Best of all would be if everyone being photographed had to opt-in before a sale could be made. That would be a company taking privacy seriously rather than trying to profit from breaching it in bulk.
Loads of people complain about the NSA's bulk data collection for the purposes of national security, but we barely see any opposition to bulk aerial imaging such as this, despite it being even more of a privacy breach due lack of safeguards around who can obtain and exploit such data.
