Apple doesn't inherently prohibit programmatic messaging. In fact, they actually developed Applescript for people to do that. What they are against is spam and abuse. Therefore, as long as we stay compliant and prevent spam, Apple is not necessarily against this.
How are your financial incentives aligned against sending spam? From this side, your words seem hollow and the typical viability of these businesses relies on sending spam.
They developed AppleScript for people to do this individually, at limited scale.
Push notifications, attached to an application or website, and controllable by a user on that basis, are the solution for corporate messaging at scale.
This will get you banned. It’s not a question of if, but when. Users will hit the report spam button. Apple will shut you down.

Apparently, they are against ANY commercial messages. Even if I personally sent marketing messages and typed them myself. So of course they are not going to like you making it easier for people to do that at scale.e
Technically, you are right that being programmatic is not the issue (so presumably those openclaw adapters are okay).
But let's not mislead investors or customers -- Apple has clearly stated your use case is not welcome (except through the iMessage Business Program they control).
