Why would I do that? I'm not a domain expert in chat apps, and I've already got my own projects and software to fix. If I'm going to take on the maintenance of some chat app, why wouldn't I just build the whole ass thing myself from the beginning? Or, more prudently, why wouldn't I just skip over this one and find a chat app that's got a track record of continuing support so I don't give myself a headache down the road?
If you can find or build something better, nobody's tryin' to stop you from doin' it. To the contrary, the world could certainly use more decent options in this space. Having choices is a good thing. :)
"why would you need features on the thing on which the vast majority of your company's interactions and unofficial note keeping and knowledge building is happening" is a fun question to ask, when the project in question doesn't have bot actions or webhooks.
