It's no longer owned by Yahoo! but by Automattic (WordPress) now. As for decentralized, they've posted recently about their intent to support ActivityPub.
The problem is not about the broadcast capabilities, they already support RSS.
The problem is about their content censoring. I don't reckon Automattic reversed the "sexually explicit" purge initiated by Yahoo. I'm not interested in a social network that censors ~30% [1] of the global art production. For now Twitter is the better place for relatively free content sharing.
[1]: Number pulled out of my hat, but the human nude being the most popular drawing subject ever, I wouldn't be surprised if this is close to reality.
