Sadly, ProtonMail Bridge is not yet available for Linux. I have been a long time user of ProtonMail, with a paid account. More than happy to pay the few pennies they ask for benefit from their premium products - even if I do have to wait for this one.
OK, I could look, but maybe I can just ask So does ProtonMail support encrypted email with non-ProtonMail users via standard GnuPG? As, you know, CounterMail has done since forever.
This is very similar to Tutanota's stance, who have had a paid Outlook plugin for a long while - idea being that this is business email that a business should pay for to keep the service going. ProtonMail still doesn't support U2F which is a terrible shame.
Yeah they have to pay for bandwidth somehow, I have used proton mail on android but I have some doubts. I emailed their tech support to tell them their app keeps trying to get my location. They expressed surprise at that, like they didn't know it did, but when I offered to examine their app source code to find out why it was doing that they refused haha. Go figure.
I'm really sorry, but the ONLY data thing I'd use a mobile phone for is as a tethering hotspot with a VPN. The lack of Android updates plus the disgraceful app ecosystem is very dangerous. And I'm livid that these apps can use my contact information that other people have uploaded to their phones.
Well, I would only use an Android phone which is supported by LineageOS and, thus, gets frequent updates. I've been using it (and its predecessor CyanogenMod) for years, they do a heck of a job, IMHO. You can use it without the GApps (which is the default) which means that you get rid of Google. Unfortunately, in that case you can normally not use apps from the Play Store (but there are ways how to get around this problem). But one should prefer open-source apps from F-Droid anyhow. The permission system (Privacy Manager in LOS) is not bad and blocks, e.g., access to your contacts. With DNS66 and various hosts files most ads and trackers are blocked, and with AFWall+ you can prevent any app accessing the network. So altogether you can pretty well control what's allowed on your phone and what is not. But most users do not make use of these options.
@summerheat - yep, understand I can root the phone and regain some control. But as you pointed out, most people won't do that, and they leak my information with no ability to get redress, no consent on my part. In any case, I prefer to stick with an external device I can harden separately and which has a distinct address space. And LE wonder why people want end-to-end encryption with PFS.
Well if you actually knew anything about proton mail you might say that without the sarcasm, but as you obviously dont, you might read what it says at the forth subheading on their own webpage at, https://protonmail.com/
This is actually OT - so just to clarify: What I said is not about rooting. 1. LineageOS does not come with root by default. Rather, you have to enable it separately. 2. The permission system in Android has been there since (I believe) v. 6. The Privacy Manager in LOS is just more powerful, you can, e.g., restrict access to personal data for all newly installed apps by default and loosen those restrictions if required. In either case root is not required. 3. Yes, AFWall+ needs root. However, there are excellent alternatives which do not require root, particularly NetGuard which creates a local VPN on your device and blocks ads/trackers/malware sites with a hosts file. Rooting a device has certainly its benefits. But my point is that even without root a lot can be done to protect your privacy. But granted - installing a custom ROM and getting rid of Google is not necessarily trivial
