I just wanted to thank OP for this thread since this is quite enlightening about sex workers/industry in general. From where I come from, sex work is technically illegal but not very enforced. But those things also make it hard to regulate the market and make it safe. I learn so much and a lot here.
As for my opinion before I read about all the intricacies of sex industry, wank it first to think with a clear head. Then if you happen to come to the same conclusion, hey, more bang for your bucks!
I think that is quite a different thing no? Those are standard vs open source implementation. Standards make sure we can interop and we can have some high level assumptions/expectations about something. But open source means we also know HOW does it fulfill the standard. A calculator can perform the operation 1 × 4 just fine, but we won't know HOW it does that. It could be that they have a dedicated circuitry for it or its using the addition circuitry with a parameterized loop.
