It’ll be interesting to see how it turns out for them. I’m a fairly casual user of Jellyfin - not enough that I’d sign up on their forum or regularly read it, unless I specifically needed tech support. Unfortunately though that means that I might miss out on updates and if there was any (relatively easy) tech support questions I won’t see them and be able to contribute. I suspect that the pool of people they interact with is going to be substantially smaller on their forum than it was previously.
