This blog post announces Proton Mail's Linux Bridge—a tool expanding secure encrypted email access to Linux users. The content and technical architecture strongly champion human rights protections, particularly privacy (Article 12) and freedom of expression (Article 19), through end-to-end encryption and a freemium access model that removes economic barriers. The company's explicit mission statement—'Privacy by default' and 'your data, your rules'—and Swiss incorporation reflect institutional commitment to rights-protective infrastructure that operates at scale.
