I find it funny how every single service builds out a community infrastructure, complete with messaging for near-synchronous and more async communication.

I've always been a fan of distributed resiliency but when it comes to basic communications, I don't have the time or motivation to hunt down the service and method of communication within that service some person chooses to use. I much prefer ubiquitous communication, at least from a user interaction stand-point.

Older messenger applications often supported handfuls to dozens of popular communication systems so you could interact with one touch point/interface, and coukd still benefit from the fact the marketplace was forcing some competition while your communication wouldn't be strangled by some single private entity's policies or actions.
