From my perspective, this is a good revenue stream for Atom & might boost their CTR - which is then another marketing point to go with Atom.
From the finance pov, their overhead costs will decrease due to lower internal admin costs.
But as others wrote, TM-related issues, bots that might abuse this feature with spamming - in the long run, they must establish a robust monitoring system to track this. It's currently in the early stages, so Atom should be careful - even Domain Parking is abused with specific tactics, even after multiple years of going live.
The other point is: How are they maintaining brand consistency? Are "brokers" getting a guideline or something?
But I can repeat the others: Keeping the TM-related stuff safe, setting clear boundaries, and implementing strict consequences are the most important things. Otherwise, I see an ample compliance & risk mitigation topic.
Those business ideas often come with knowledge-sharing & community-building to exchange and teach the "brokers".
Im not much into this topic of Atom; just read the OP Article and the comments.
But
@Future Sensors Numbers show that the demand is high.
Need to read more about this. Could be a big thing; but also something that causes reputational risk.
