Nope. The article’s assertion is that governments will start to put enormous pressure on tech companies in their borders to include backdoors in their systems for LEO use. This in turn may lead to “nationalized” software e.g. what Russia and China largely do now, but in many more countries. You may have no choice but to use phones, computers, and software that is backdoored by your government - everything else will be illegal.
I think "nope" is in reference to "hacking" system. The point of the article is that hacking by software vendors that sell to law enforcement was a pressure relief valve that deflated the movement that the FBI was pushing at the time to have Apple (and others) build backdoors into their systems. If the phones could be hacked, and backdoors were not necessary the FBI could back off and still get what they want. If the FBI can't get what they want, they can either pressure the companies like Apple, or they can pressure congress to make laws requiring this. The phone makers could stand on principle, go to court, but the courts in the US are not very tech savvy, and usually deferential to law enforcement. Other countries may be better than the US, but some are definitely going to be worse.
So is a backdoor worse than a security vulnerability? I don't know but that is what this article is about.
I did, that looks pretty good for a prototype! I would suggest adding the option to send as plaintext email (disabling all formatting options), as this is still useful in some cases. Bookmarked.
No I mean sending an email fully in plaintext, see https://useplaintext.email/ (suggestions/justifications for mail client authors are near the bottom)
Also, be sure you are sending a plaintext copy (formatting stripped) using multipart/alternative, as most terminal mail clients can’t do HTML mail or can’t do it well.
