Once companies grow past a handful of employees they usually go from everyone being a generalist who can work on every part of all their product to having specialists who only can deal with some of what the company does.
The various sites that report corporate information put the number of Proton employees in the 160-250 range. They are almost certainly well into the specialist phase. The people working on calendar and VPN and whatever would likely not be able to help with mobile email if they were shifted to that. If mobile email needs more work than those currently working on it can do, Proton needs to bring in more mobile and/or email specialists.
It would only make sense then to stop calendar and VPN work if they do not have sufficient budget to bring in people to help with mobile email and need to lay off people from other projects to free up the money.
Interesting point.
At the same time, I think it won't take long at all for someone who develops a calendar mobile app to switch to working on an email mobile app. -- But maybe you meant the email web client? (Web vs native development?)
I think you're right that a VPN and related Linux kernel and networking is a different type of specialization, yes.
But it‘s not only the app that is bad, the web client was quite functional for a while apart from the missing login persistence. Then came the new UI now it just kind of works. Try to move/tag many mails after each other? Now you also have to deal with clicking away success boxes as they start piling up and overlapping the very UI elements you are trying to reach. There are threads but for some reason they are way more cumbersome to use than GMail’s. Everything is gigantic now as well. I haven‘t checked yet but during the beta I could just not find some settings anymore. Hope they got added before launch.
On this subject, I thought the recent upgrade of the email web client was nice. Maybe we can hope for something similar with mobile soon?
(How many emails do you get per day?)
In addition to the subpar UI, I was trying to import my (admittedly large) gmail mailbox into Protonmail, and it just did not work. I let it run for days, had to restart it, repeated the process for weeks, and after about 4 weeks I just had to give up…
It’s a shame because I really appreciate the security aspects of it, and the fact that they’re a small company / underdog.
But there’s just too much friction.
Very glad to see the security audit in any case.
