What is the reason for saving the end-to-end encrypted backup files on Signal backup servers instead of iCloud or Google backup service, as most of us are already paying for this storage?
The "Signal should exist" part of me is happy to donate $2/mo to help them keep the lights on, but I really did expect that to be an option alongside Drive/Dropbox/et al, not the only option.
Besides the obvious (they want/need the revenue from selling their own solution), many people using Signal do so in an effort to move away from Big Tech and/or on devices with custom ROMs.
Yes, but Signal mission is also to popularize E2E secure communication for normal users, whi usually don’t use a custom ROM.
