At the time of the announcement, the moderators of most of the subreddits involved with the community points program claimed to be unaware of the decision.
The majority of communities I followed on Reddit did not live to Lemmy, or they did and got abandoned in a couple weeks. None of the sports or gaming communities I followed are here/alive here.
Not the main communities, but the smaller ones. I’ve had to resort to Facebook for getting information and news about teams I follow, and for new indie games that get released the only communities I can find are on Reddit.
