Why it's listed

Proton Mail is listed in email hosting because it competes on utility: e2ee email at scale, non-profit owned. It's stewarded by a non-profit or foundation, which structurally protects it from acquisition-driven enshittification. Licensed Clients OSS (GPL); pricing: free tier / paid, public. Its resource footprint is reasonable for what it does, though not featherweight. This entry is provisional — the scores are seeded estimates pending our full manual rubric pass, and the verification date will appear here once complete.
