Rumble is a site full of white supremacist videos, voting fraud nonsense, and Covid conspiracy misinformation. All content that has been banned from respectable video sites like YouTube. The last thing ET should allow is embedding content from Rumble.
Everything you said is incorrect. You tube is not respectable. Either is facebook! Have you seen what facebook has been allowing lately? It's disgusting to say the least. They should ban themselves. I bet you don't even have an account with Rumble or you would know more about it.
What do you expect from individuals who spend their time posting links from Rumble to white supremacist videos, voting fraud nonsense, and Covid conspiracy misinformation. All of which has been banned and removed from respectable sites on the web.
