@lproven Sadly it's not only the companies not supporting #XMPP anymore, but also the client ecosystem becoming more and more degraded.
For example, on Mac there used to be a bunch of well maintained OSS clients, like #AdiumX. These are more or less gone, with a few exceptions like #BeagleIM and #MonalIM. Might be a different situation on Linux though...
This is sad. For me XMPP on its high was the pinnacle of IM.
