The threads hate is so fucking stupid. Companies getting involved with Lemmy would be awesome, mostly because it's a replacement for discord. The whole EEE thing is FUD, open source largely solved that problem. The people with control aren't just going to give Meta they keys anyway. Some corporate involvement could help solve some real issues with making hosting easier, reducing storage needs, and increasing federation throughput.
Corporate instances would be awesome to add to my feed for the things I want to see and it would be a way to attract people to get the more niche communities. The tools already exist for the people who don't want to see that content. If for example steam community discussions became Lemmy communities that would be a huge win for the platform.
Also threads isn't even the same federation model as Lemmy anyway and it's unlikely to ever actually federate to here anyway.
