Regulation should prevent this from occurring. If you use a product that claims it is E2E and it is not, you should be able to sue wildly for potential damages given the sensitive nature of the software.
It already exists. It's called "fraud".
On the other hand, I think things involving cryptography at scale ought to come with regulations on language
For example, look at how the word "bank" is specially regulated by most governments. I can't just call myself a bank without meeting specific guidelines or else it's not just typical fraud, it's major financial fraud coupled with putting sensitive customer data at risk.
Same here. We need specific legislation targeting these scummy businesses who use corporate ignorance as an excuse for selling a product under false pretenses of end-to-end encryption.
No, I don't. I don't want companies to lie. You can collect intelligence the same way we've been collecting intelligence for our entire history on this planet prior to E2E comms. E2E isn't a hindrance, it's a way to enforce limitations on government overreach.
No freedom is without compromise.
