I mean, their main business (whatever there is to do with the XRP coin) is pretty much dead I assume? Smart for them to just buy crypto-related companies because we all know they're far more likely to make money in the future when demand for bitcoin/crypto returns, than whatever they want to do with XRP.
Their agenda probably looks something like this: "Hey guys, you probably know already that Bitcoin is bad for the environment, so let's harass Bitcoin Core devs to #ChangeTheCode and maybe we will give you some free XRP if you hound them enough".
I mean, it's comedy. Nobody takes Ripple seriously anymore except for the banks. Probably because even it is better than whatever wimpy infrastructure they are still using from the '70s.
