The important and hard part in crypto is key management, but that's considered too complicated a concept to explain to users.
"Your Privacy Is Our Top Priority Security at the expense of privacy is not what we're committed to. Reolink Cloud collaborates with Amazon Web Services for secure data storage. Also, we use standard AES algorithm for data transmission encryption, use RSA/ECDHE algorithm for secure key exchange, and follow the TLS standards. When you save footage to Cloud or play clips back, your personal information is always kept confidential from beginning to end."
When they tried to encrypt photos end-to-end much of HN (and others) flipped out and raised such a fuss they gave up.
There is no evidence that iCloud was going to implement end-to-end encryption. This was a rumor that was spread by people who defended Apple's plan to implement on-device CSAM scanning.
That must signal some widely-objectionable, obvious implementation error that rubbed common people and engineers the wrong way.
That said, the option should at least be available to those who know the benefits and accept the risks.
We must not forget that most of us over here have affinity with technology to at least some degree.
We might manage just fine, but it's way above our grandparent's heads.
