IDK. With safety angle, maybe. But Slack is the opposite of "Healthy Internet". It's a corporation that wormed its way into companies and communities alike, by doing "embrace, extend, extinguish" on IRC to gain initial organic marketing from naive techies. And they've paved the way for Discord making so many good communities no longer accessible.

It's not the kind of association that makes Mozilla look good to me.
