I think they just see the stable coin market and want to tap into that. I hear that trading volume on stablecoins is usually higher than Bitcoin. There is a huge demand for stablecoins, unfortunately because they haven't done much research as to what bitcoin is.

I don't think we need it on bitcoin, but like with other ordinals/inscriptions you can't really stop them. I also think the LN network needs to work a lot better for this to get any traction.
