All good except that Grafana Cloud is super expensive when you consider it per metric. This probably is the most expensive service per bit of data!
Surprised to hear this as none of our Enterprise plugins had a change in licensing (i.e. going from free to paid, or shifting within paid tiers) as far as I am aware. Would love to dig into this further.
If you're up for it, feel free to send me a note at divy.goel@grafana.com or let me know how best to reach you!

As this is not how we (try to) operate, I also had a look.
From what I could find, it seems the account you are referring to is a very early Cloud account. For reasons I don't know and which might be lost to history, your account had an old and non-standard license attached to. From the viewpoint of today, the license itself seems broken.
To be clear, that is neither your fault nor do I believe you could have caught it even if you looked. While there was no change in the licensing requirements on the plugin, an upgrade to a significant rewrite of the plugin "fixed" the problem of accepting a broken license. That "fix" meant the plugin stopped working.
Again, this is not your fault. But it was not a deliberate action by Grafana Labs nor caught by our testing, either.
I believe your company is in contact with David Dorman, our Head of Self-Service, about this. If you'd like me to ask him to follow up with you directly as well, please let me know how to best contact you.
I'm curious—what other sorts of services are you referring to in your comparison?
