Considering that all other alternatives are either
- extremely difficult if not impossible for non-technical users to leverage, or
- much, much worse, up to even eagerly giving out your data
I consider Signal to be the best option out there. It’s not perfect, but nothing is. It simply is the best general option out there, by far, for a general audience.
Yes, you can be totally secure, untraceable, and ultimately unfindable. But being cut into pieces, with each separate piece entombed in its own barrel of concrete, and each barrel dropped into a different oceanic trench, tends to be a bit beyond what I consider to be reasonable to achieve that.
