Sorry to repeat myself, but like I wrote in my previous post the default chat client for Fedora Workstation needs much better Office 365 and Lync integration:

Most organizations and academic institutions are migrating to Office 365 as they reduce their in-house physical server count, consolidate licenses and go "to the cloud".  These same organizations also have a large inventory of existing Windows desktops that could be turned into Fedora Workstations instead of taking the expensive route of buying Macs. There's a huge potential WIN here to provide major cost-savings to organizations and provide a cutting-edge Linux environment that will beat the poorly implement UNIX-like environment of Mac OS X.

2. Empathy/Pidgin currently doesn't support enough features from Lync (now Skype for Business) [1] - the Microsoft enterprise communication tool - and that's a show stopper.  You can't do video calls, you can't initiate meetings and you can't do screen-sharing or file-transfers.

The real problem is integration with enterprise services and that's the big challenge ahead for Workstation.

According to the WG product description for Fedora Workstation you want to target university, enterprise (corporate) and tech-companies and that pretty much comprises 90% of the users you want to attract. Most users in the real world (corporate, university or tech-company) use Google Hangouts, Skype or Lync (now Skype for Business) and in some cases just plain IRC.  For meetings there's typically Goto Meeting which currently has no Linux client.

Therein lies the biggest issues with Telegram: it depends on proprietary
server code and also federation is not planned.  I consider these to be
significant problems. Telegram 'promising' to release the code to
their server is not good enough in my opinion.  I hate to go
Stallman (although I have the utmost respect for RMS) on you but
Telegram users are still tied to the perceived and/or actual benevolence
of the server vendor.

Tox is already p2p and cross platform.  The only cross platfrom FOSS
voip application that springs to mind is Jitsi.  Tox works through a
firewall; both my machines have the default firewall settings from the
netinstall iso, i.e. fairly restrictive.

If popularity is an important criterion then surely Skype would be top
of the list for inclusion in Fedora and Gnome.  For reasons too obvious
to state that won't and shouldn't happen.  There appears to be a
chicken-egg scenario here unfortunately with regards to Tox.
