I would very much doubt that.I'm convinced they're only doing this vegan thing to keep with the trend. They probably eat bargin buckets from KFC behind the camera.
Yes they are fake and totally money obsessed now but those things are completely separate from their Veganism. Or plant based diet as it seems more likely now. You can see a genuine passion at least for the health side of it.
Plus once you get past him is like Veganuary, very few vegans are or became vegan as part of a trend.
They might not be the brightest and far from perfect but actually being vegan/plant based is the one thing they’re not faking.
