JAMF cannot make any sense out of Apple's disastrous Apple IDs

We have been using JAMF in conjunction with Apple Business Manager across our whole organization. Central to everything Apple is an Apple ID -- for buying and registering hardware and software and getting support. Apple provides absolutely no transparency or management capability with Apple IDs (e.g. you cannot merge Apple IDs). We were attracted to JAMF as a way to manage Apple products in the absence of Apple providing such ability. Instead, we were just engulfed in a maelstrom of unnecessary complexity and jargon for which the time invested will never show a return. If there is any benefit to using JAMF, it is not at all apparent. If you value your time, I seriously do not recommend JAMF.
