Once again, really confusing messaging from Microsoft. I think most people would appreciate it if marketing either said, "Over time Viva Engage will replace Yammer" or Microsoft took the time to tell us how Viva Engage is different.
Microsoft doesn't have to be its worst enemy regarding FUD- Fear, Uncertainty, and Doubt.
Yammer and the whole Enterprise Social Networking concept is great. We know that Teams is for high velocity, small team communication and collaboration. We have seen that Yammer has struggled to keep up with the likes of Workplace by Meta/Facebook. Viva Engage looks great, and I would welcome an announcement that said it will eventually replace Yammer as the primary way to communicate and collaborate with large audiences.
