Two problems I see with the authors argument. Maybe someone more knowledgeable can chip in to correct me if I'm wrong:

1. Aren't E2EE systems designed to prevent decryption of content already created in the past sitting on the vendor's servers? Yes, the vendor could go rogue, but, assuming they currently have implemented E2EE right, it means any change to the client can only compromise content created in the future from that point onward, no? So why is the article implying Apple could have provided a back-doored iOS to bypass the encryption for existing content?

2. I also don't find the argument that E2EE is only a legal trick fully convincing. There are several other incentives for a vendor to implement it apart from avoiding legal issues: preventing insider abuse, reducing liability, improving customer trust, and resisting mass surveillance

These are real engineering motivations. The threat model is not: "Protect you if <vendor> becomes actively malicious tomorrow." Its more like "Protect messages stored on <Vendor>'s servers from attackers, employees, hackers, routine legal requests, and passive surveillance."

Alright, I'm ready. These are engineering motivations, as you said. So, which one of these isn't a cost center? Because an insurance policy would handle the first two, but probably cheaper. Customers have repeatedly proven they will buy the product lacking the trust. Resisting mass surveillance? They are the mass surveillance. Which is now a legal compliance based cost center.
