> There are alternatives

Can you name one smartphone device with open internals? I'd love to buy one, but I don't think they exist. From Replicant's recommendations [1]:

If compromising on privacy/security is not an option, or anything serious is at stake (e.g. political activism or journalism in a sensitive area), it is advised to avoid using a telephony-enabled device at all.

My impression from the smartphone market is that phone platforms have become less open, not more, over the last ten years. The PinePhone isn't generally available yet, and the Librem 5 current iterations don't have working audio calls.
