Independent mentions

  • Proton and Standard Notes are joining forces / Hacker News — I have a feeling that Proton has too many different products, and inevitably, like their greatest competitor, the google, they will be forced to wind some of them down. And that will make some users mad. Proton Drive still does not have an option to sync files from Linux with no ETA. Introducing new products and not caring about existing products sure shows company's nearsightedness. And even if I am paying customer, they are still pestering me with upsell promotions, to use their other products
  • Ask HN: Have you migrated to Proton mail/calendar/pass/etc.? How was it? — I used ProtonMail for a few years, but ended up switching to FastMail. Too much became too difficult due to the full E2EE, especially the calendar app was impossible to use together with other apps or even other people. The email app was fine, but not great, and again E2EE was difficult to use with other apps. Especially on desktop I like using a dedicated app, and their bridge just never cut it for me in terms of stability. The VPN worked well! I ended up switching to Mullvad, and have now mo

Limits and method

23

Limitations and open questions

Known constraints and missing evidence from the collected pages.

The collected pages do not mention specific competitors by name. Evidence gaps include lack of detailed pricing for Proton Family storage, no explicit uptime or status page information, and no independent review ratings or scores. Open questions remain about the exact scope of enterprise features and any limitations of the free plan beyond storage.

24

Sources, method, and limitations

Evidence inventory, collection method, provider use, and constraints.

This report is based on 15 collected pages from proton.me, including product pages, pricing pages, roadmap, and support pages. The evidence catalog includes 180 items, with sources from Proton's official website. External proof search was enabled but only verified the existence of linked results, not their content. Pricing data was cross-referenced with authoritative pricing tables. Limitations include potential bias from vendor-published information and lack of independent verification of claims.
