When the Japanese user base goes down 20% it won't be news anymore.
I also find it interesting that they are turning to Weibo, as this was a pending question. A lot of other mainstream artists started or repromoted their official Instagram account (I don't think there's serious surveys out there. Out of the 100+ I follow about half had comments on thinking of it as a backup plan), but for the artists that don't match Meta's rules the only other obvious choice was mastodon, and in Japan they already got burned a first time with Pawoo and the earlier mastodon boom.
