As far as I understand the NPOSL-3.0, cloud vendors would definitely count as for-profit, and therefore not be allowed to use the software, even in an aggregated way. They would have to obtain a separate license.

The NPOSL doesn’t prohibit for profit licensees, it includes a declaration that the licensor is a nonprofit, which may (where true) in some jurisdictions increase the effectiveness of warranty disclaimers.
For-profit entities can use NPOSL software freely.
Yes, but the sweet spot for many services is the ability to offer hosting while allowing self-hosting, free dev licenses, and third-party integrations. It's a particularly good no-brainer sales story to contrast with self-hosting dominated by admin/HR, and possibly hardware/data center costs.
