The Signal messenger and protocol.

I wrote it to preempt comments about complaining without telling anyone about my concerns.

I completely understand your view and agree that Signal went in a different direction than I wanted or needed.

I didn't use it as a primary SMS replacement, rather that was the "hook" to get a bigger customer base amongst my contacts whilst sneaking encryption capabilities in by the back door.

I mentioned RCS because a messaging app that integrates with the common platform of SMS and RCS would bring end-to-end encryption capabilities to even more people. I could imagine integration with other messaging protocols too.

The original UI for Signal made it very clear if something was encrypted or not. Right until someone decided to introduce custom colour for each chat, essentially killing the clearest indication of security level.

A smarter person would have changed colour depending on level of privacy for example.

The crypto donation was just weird and put me off ever even considering making one.
