The article is from a security researcher involved in the development of post-quantum encryption. Hes known for fighting against various agencies trying to weaken encryption for their questionable benefit. Hes been very successful but a one-man-show only goes so far. Please, if you read this: write those emails to the mailing list and tell others whats going on!
This (sadly) has implications across the whole world, but right now its very easy to stop.
And please, if you do write the email, please dont just copy paste the template in the article, it seems the comitee wants to ignore all the ones with the same wording because of "spam"
