Do you have actual examples other than companies enabling speculation or worse when they can safely take a cut? PayPal "adopted" crypto (and by extension blockchain) in the sense they will let me buy and sell for a fee. I see that as analogous to a grocery store selling cigarettes -- they haven't "adopted" or endorsed tobacco, they just sell it because they can make money.
