Apparently someone is trying to form a "MisskeyHQ Ltd" company, according to this one single article that was shared around fedi earlier. I couldn't find any other sources but that may be because other articles are in Japanese.
From my understanding of the article, the misskey.io administrator and syuilo will be part of the company. The goal of the company is apparently to ""better organize" misskey and misskey.io and secure revenue? Not sure how a company is going to help with that.
