Well, they're losing one advertiser - me. I was about to start an advertising campaign on Reddit when this all went down. Just pulled the plug on it. At this point, keeping my Reddit ad will be bad for business with my client base.
Not sure where I'll advertise instead, but definitely not there.
That's why I am staying on Reddit for now. I haven't found an equivalent to the kind of support group that I am in, at least not yet. Someone has actually started one in the Fediverse, but it's empty, so not too terribly helpful as yet.
Maybe if the moderators leave and the group gets overrun with trolls, the users will go elsewhere.
