Same reason all the above companies got into Beanie Babies: To make money.

Right. I'm still asking where is the 'use case' in beanie babies vs cryptocurrencies, or stable-coins like what Stripe is using it for?

Stripe is happily selling pickaxes to gold miners, as they say. They are more than happy to collect their "useless" fiat USD, and play along. I think it's ethically dubious, but... that's another story. It's certainly profitable.

And that somehow is a problem? Is that why it will be 'totally destroyed' and banned then?

Surely both you and the author are going to be disappointed and have to complain a bit more if you're looking into 'destroying' it all.
