One redditor asked about it on the most recent AMA:
Hi, is there a plan to release protondrive for linux?
Proton CEO’s answer:
We’re currently looking at options for how to fund this. It’s an expensive development because Linux has so many different flavors and we need deep integration with the filesystem, and it is not yet clear if there are enough Linux users that would allow us to offset the cost of this development. Like many things Linux, it may eventually just have to subsidized from Proton’s reserve budget. That doesn’t mean it won’t get done, it will just take longer since we are also subsidizing several other efforts at this time, such as the Proton VPN free servers for elections campaign: https://protonvpn.com/blog/free-servers-before-elections

6 months ago he said: “We want to, but we can’t find Linux developers.”
Seems like they would first look if there is enough money and enough users to make it worthwhile, and then go looking for developers.
Don’t get me wrong, i have been a paying client for many years and really love the products and the company, but everything they say about linux… I don’t know, this just sounds like an excuse to continue to prioritize other things and get the linux users off their backs for a while longer.
Not sure what’s the chicken and what’s the egg here but maybe they didn’t know how much work would have to be done and thus how much money it would cost.
But it’s all just speculation and neither am I trying to defend them nor do I have a use case for this particular feature. I just wanted to interject a different possible scenario.
I always see people asking for it, but I guess we’re actually the vocal minority in this situation.
It’s unclear that they need to handle a specific flavor when they could release a Flatpak. I think the community wouldn’t have any problem tweaking the dependencies for particular distros.
It wouldn’t be the distribution method that is challenging, it’s the complicated task of monitoring your filesystem for changes, and working with a dozen or so different file systems to do it (the way it’s accomplished on an ext4 partition might not work on btrfs, for example).
I’m not skilled enough to be able to speak to that.
Maybe I’m in the minority, but all I need is a fuse plugin. I don’t need specific syncing like a OneDrive/Google Drive app.
ProtonDrive bridge (like they have for Mail), that handles the encryption, that exposes a localhost webdav endpoint that can be mounted.
This would be a pretty reasonable comprise in my opinion. Works like mail bridge (maybe calendar could get some love too?) And everyone is happy.
It’s not fancy like an automatic folder sync thing, but at least I could mount a Protondrive directory and do my own syncing myself (I’m a Linux nerd afterall). There is no need for “deep filesystem integration” as he claims.
The same thing could be used for Calendar with Caldav feed as well. A single “Bridge” app could me made to handle Mail, Drive, Calendar
I really don’t blame them, security and privacy minded folk are more likely to use niche configs. Feels like for Linux stuff companies may be better served making APIs and letting the community handle it. Rclone for example implements a bunch, and last I knew had an unstable Proton plugin.
