After merging two companies I had to move a bunch of stuff over to a new bankaccount. three weeks later and I'm still not 100% sure that I got it all, the interfaces are so opaque and the different ways in which you can get billed so confusing (never mind the bills themselves) that it is nearly impossible to get a clear picture.
This does not feel like it is an accident, and this message is very much in line with that.
I always wonder how such systems come about. The number of confusing error messages you have to deal with for pretty basic stuff is off the scale. You can name anything, except of course when it actually matters and then only some cryptic UID is shown. Don't get me started on users and permission management, or how it is perfectly possible to orphan an entire project[1] if a person leaves your org. (Gsuite and GCP may superficially appear to share a bunch of stuff but that just sets you up for some very cute surprises, from which it can be extremely difficult to recover.)
