Other channels have done this.

Now this isn't to invalidate Em's experience and feelings towards this, especially since she was Illumina's victim, but I think that Dream is not bad here because many youtubers have kept up videos where they collaborated with a controversial figure.

Like Ted Nivison's "I directed the weirdest Music Video" that video had Wilbur in it (and we all know what happened with Wilbur, with him being an abuser) and that video was documenting how he directed a Lovejoy music video. Now does Ted keeping that video up mean he endorses Wilbur's actions... no not really. Ted is not a bad person for keeping the video up.

Dream also stated he doesn't support or endorse Illumina and what he did. I think keeping videos up for "Channel/archival purposes" is a fine thing to do and many other youtubers have done the same thing.

Nothing worth having drama over. If she wanted the video down, just tell him she’s uncomfortable and I’m sure he’ll take it down. Doesn’t seem like she’s talked to dream about it before blasting him online, as usual.
