Look up their terms of service before considering it for work use. At the end of the day Discord is not enterprise software, and so will never be considered seriously for it.
This is a good point, one of the points that my friend made is that without a comparable revenue model you always run the risk of Discord shutting down whereas Slack wouldn't. With that said, I would happily pay for an enhanced nitro subscription to discord that allowed for enterprise use
Some SLAs at the very least would be nice. At present they don't even guarantee that they won't delete your data randomly for any or no reason.
