It makes a big difference. If I print out the texts I receive, it doesn't change whether the texting program is end-to-end encrypted. The same goes for backups. An unencrypted system-level backup doesn't mean that the program being backed up is failing at security.

It's bad that Apple doesn't let you encrypt your backups properly, but it's a separate issue.

What if the texting program has a built in feature to print the texts you receive and mail a copy to the company that wrote the program, and it nags you to enable this feature all the time, and most of your friends have it enabled? Because that's a lot closer to the scenario here.

iOS programs can choose how their data is backed up. iMessage isn't just getting its data stolen by iCloud accidentally. These backups are a feature of iMessage as much as iCloud. And besides, iCloud is made by the same company, it's not a separate entity.

iMessage itself bugs you to enable backups?

Well desktop apps don't. Would you say that no desktop app that saves its key can ever qualify as end-to-end encrypted?

I'm not convinced that's relevant to whether the encryption is end-to-end or not.

I would say that no app can qualify as end-to-end encrypted if a large fraction of users send their data to the maker of the app in a form that can be decrypted by the maker of the app, regardless of the reason.

If iMessage was made by a third party and worked exactly the same then you'd have no objection to calling it end-to-end encrypted?

No. This is a necessary condition for being end-to-end encrypted, not a sufficient one. But iMessage doesn't meet it.

Okay, so if I can't guess your point of view, then it would really help if you would answer the question I asked about desktop apps.
