These may be perfectly legal (example xxx sites), gray at worst (like anime websites). Some anime site that had (for example) paypal for over 15+ years. Plop ... gone.

Crypto has become become the alternative payment method for those sites. So its not "dictators that are doing pretty nasty stuff" but a ton of sites and services that can be affected.

Ironically, there has been a lot of focus also in Europe regarding this issue, as much of the internet payment processors are in or linked to the US. With the focus to get a alternative to Visa/Mastercard going.

The reality is that a lot of power regarding payment processing is in the hands off one country, that has a lot of large companies with interests/powers to dictate over the entire world, what is and is not allowed. And crypto has becomes a necessary evil. In a ideal world we do not need crypto as payment processors are neutral or at minimum have very stronger requirements to kick off clients. But the reality is different...
