Hmm, what do you mean? I'm talking about using Zulip instead of Slack. If I'm going to use another similar service, I might as well use Slack itself. Zulip is miles ahead.
I'm saying my employer, who pays for slack so this whole thing is a no-op, means I have to have slack open. I'm not adding another chat platform to my repertoire, that is the real problem of incumbent
If you read the CUE discussion I linked, you will see several people making this same point
Well yes, how could you? If the rest of the company is on Slack, you using a different service wouldn't work. The question is where does the employer (or, specifically, the CUE team) go if they don't want to pay for Slack any more.
1: I am not employed by CUE. I am their biggest fan and cheerleader
2: CUE has never paid for Slack
The context is that I have slack open, I am in 12+ groups. I've tried adding other platforms like discord and keeping them open.
The point is that, as a human, I only have so much attention, and having more than one chat program open at a time, in addition to the other messaging streams we are subjected to, it's a non-starter.
For my own sanity, only one chat platform can be regularly open. Thus follows the network effect and incumbent arguments
