This article doesn't just summarise the discussion on Proton's blog post (which the article linked to), it's looking to spread the information and increase discussion of the issue, in particular in the community of users who regularly browse their site and comments sections.
Your comment is like complaining about reposts. Yes, in the worst cases reposts can be bad and disruptive, but more often than not it's just a genuine attempt to spread the content/story further and one that introduces it to more people than the original. This isn't one of those worst case examples.
Articles like this are at least better than Yahoo or MSN articles that literally just copy the text of other publications (although sometimes the source article is paywalled while the copy is not).
