>If you read the link you would know that contrary to your expectation other apps advertising E2EE don't allow the app maker to read your messages.
What does that even mean? Suppose icloud backups doesn't exist, but you could still take screenshots and save them to icloud drive. Is that also "Apple has always been able to read encrypted iMessage messages"? Same goes for "other people having icloud backups enabled". People can also snitch on you, or get their phones seized. I feel like people like you and the article author are just redefining the threat model of E2EE apps just so they can smugly go "well ackshually..."
It means, for example, Google Messages uses E2EE backups. Google cannot read your E2EE messages by default, period. Not from your own backup, not from other peoples' backups. No backup loophole. Most other E2EE messaging apps also do not have a backup loophole like iMessage.
It's not hard to understand why Apple uploading every message to themselves to read by default is different from somebody intentionally taking a screenshot of their own phone.
