Do they have the resources? Sure. But that would be fiscally irresponsible. Why would they try to replicate proven tech that works well and offers everything they need? Signal is available, accessible, and easy to use.

I also should clarify that when I say it's a primary method, that does mean one of many. We have fallbacks. Losing access to Signal wouldn't cripple us, but it would be an incredibly stupid self-inflicted injury. Having easy and accessible means of secure communications is important because it prevents people from resorting to insecure means. People are lazy and the best security is always the security that people least mind using. That's why Signal matters. Not because wec somehow wouldn't be able to hold secure communications without it. I apologize if my previous comment was misleading on this.
