Those are work tools. If you work for a company that uses them, you ought to have them installed on your work machine. This is not unreasonable.

If your friends are using random apps, screw them. They'll find a way to get a hold of you if they care enough. Or you'll eventually figure out what the majority are using and cave.

I covered that with "It might be fine in certain contexts (e.g. team members..." and "it breaks down when you're communicating with arbitrary members of the public". A lot of the comments in this thread seem to be assuming that the only communications that ever take place are intra-company. For many people that isn't true at all. For me the vast majority of work-related communications are to clients and third parties. I can't just say "screw them" or "they'll find a way to get hold of me if they care enough" or tell them to use slack to inform me that they've emailed me. I have to live in the real world.
