Unpopular opinion: I think it's wild that ANY ORG would pay $200k for a chat app.
If I ever ran an org that needed a chat app and the costs came even close to $200k a year, I would rather hire an engineer, contract a designer, and create our own, or more likely, contribute/fork an open source project like Matrix; providing us with the ability to *really* integrate it into our company/tools - as oppose spending it on IRC+ for "good enough" integration. PLUS ... our data stays on under our control.
