It's actually quite simple.
In case you forgotten, you said: 'All crypto is a scam.' [0]
That means everything including anyone who is using it, or has holdings or are insiders which includes Stripe, Moneygram, Square (now Block) and especially Signal who are still directly involved in the entire scam. All the ones I've listed either got no backlash or did have some but never removed their crypto products, which certainly still makes them fully involved in the entire crypto scam as they continue to offer it.
Trying to give exceptions to companies like Moneygram and Stripe, Square, etc is legitimising their crypto offerings as a 'use-case' which contradicts what you said with it all being a scam, since we both know what they are offering is nothing but still a scam which they are all involved in.
There is no mental leaps here, No exceptions or any use-cases with that statement. If another commenter got the point straightaway [1], it is not hard to recognise that.
