I switched to Infomaniak when I first started seriously migrating away from gmail. I found it a really clean and almost too good to be true, email is fundamentally un-private and IK seemed like a great balance. Also all their apps were open source and on fdroid! Wow!
I was disappointed to see them take a stance against Swiss encryption law, which ultimately made me stick with Proton (also not perfect, but who specifically took the opposite side of this proposal). This issue seemed to be at the core of what I expected from a privacy focused email provider.
What really made me upset was that when I then tried to leave Infomaniak I found that they lock email forwarding behind a paywall (something not even Google does). It actually became very difficult to leave the small number of services I had migrated over to, and I still have my ikmail in my client by necessity.
This is definitely a positive change. I want to take them seriously and more competition in the relatively private non-American email space is good. But I am still hesitant to reccomend or embrace them. Would be curious to hear anyone else's thoughts?
