Personally I believe that it’ll make people associate the Fediverse with Threads, which is not a good thing. Edit: It’ll replace their definition of the Fediverse, with Threads, and people may widely forget about Mastodon, Lemmy, Kbin etc.
It’s coming wheather you want it or not. It may be best to figure out how to be receptive to it.
Detrimental
I hate that its tied to Instagram.
I feel like federating was sort of a fallback plan so they they could claim fediverse user numbers for the platform if the launch went poorly. Since it seems to have been successful I’m not sure they will even bother federating or care if everyone else de-federates from them.
beneficial or detrimental
i’d say rather inconsequential in the longterm
