Not mentioned by the OP but Telegram also released an update last week to its group voice call feature, which essentially turns a channel or group into a ClubHouse room. https://telegram.org/blog/voice-chats-on-steroids
Discord joined the party as well and just rolled out Stages which is basically the same thing as Clubhouse. That’s going to be super useful for us though as we quite often present to our largish community so having better moderation control is going to help out a lot. I also think having this at the community level is going to be far better than being thought lead at by people who love the sound of their own voices.
