I think Ian genuinely believes he did something horrible and needs to repent for it.
Showing his massive autism once again. He's surrounded by the woke crowd, including in his bedroom, and hears nothing but different forms of "whites bad" and takes that shit to heart, because autists take everything literal and have a hard time realising when they get lied to. By now he probably thinks saying the nigger word a couple of times is as bad as being a buck-breaking plantation owner from the 1800's because that is what all these wannabe race baiters and assorted grifters, first and foremost his own fucking wife, are telling him all day erry day.
Edit:
I think he tried to do it for financial reasons and is panicking because it isn't working for him like it did for other edgy attention whores
Because he lacks the business- or rather grifting acumen all these other, previously "edgy" Youtuber rats who did a 180° from their old content posess. Again, i'm convinced this stems from him being on the spectrum. Look at a weasel like Ethan Klein, all his actions were completly calculated, he noticed the tide is turning (no doubt being tight with Susan Polacklastname helped here) and was one of the earliest people to adapt his content to a new, wokeness-poisoned audience.
Sure, his new content is shit and he's a miserable blob but at least he's crying in a million dollar mansion and his fans are still lapping his shit up.
His hideous wife is another good comparison for being smart from a business standpoint compared to the Jomha's, Hila generated another income stream via her shitty but expensive clothes line, so these two won't be destitute should the YT shit ever crash and burn. Anisa organized charity events that, in the end, cost them money instead of generating it and she also didn't manage to gain a bigger audience from those events for Ian's content, the numbers on his recent videos are proof of this. This is due to Anisa only craving attention for herself instead of something more important like, you know, financial stability. And of course because she's fucking incompetent.
