I think they’re trying to get off of it because it is so freaking expensive.
We moved vendors a few time and it wasn’t that painful.
Fact: I'm not going to hear my phone ping in the middle of the night. I'm much more likely to hear my phone ring.
That said, every other product in this space is crap. I'm not sure why though. This seems like a pretty good market for disruption. Maybe there is some hidden "problem" that I don't know about.
