Proton Blog has some good articles, here is a good one which the topic was mentioned on Surveillance Report 150 related to EU Chat control.
Nice to hear how Proton stands on chat control as a lot of us use proton services.
Not just a fan boy of Proton. The Surveillance Reports are better than professional. Every report has show notes and time stamps. The blog from Proton reminded me of the report where I jumped back in the video with the timestamp, watched what I needed. Followed the resource link to the article.
