Today, we’re launching the Proton Drive app for Mac OS as a privacy-first alternative to iCloud Drive. It’s a significant milestone for us because Proton Drive is now available for all major platforms, including iPhone, Android, Windows, and the web app. We’re here thanks to all of your feedback on the Mac OS beta over the past few months. Thank you.
That is exactly the point. The Linux userbase is generally more privacy oriented and thus available on Proton‘s channels, be that Twitter, Reddit or here.
However that doesn‘t mean that in the global numbers of >100m accounts there are that many Linux users. There it is indeed < 1%. Without offense, Linux users are a vocal part but in the big picture a minority.
That doesn‘t mean there won‘t be a Drive Linux client. It just means different priorities in releasing for in advantage for the bigger platforms first.
