its not really hidden..
firstly and mainly its about anyone wanting to run a payments service needs to register as a MSB/MTS which means costs, time and accreditation requirements.. thus it creates a barrier for small business to operate.

i understand oeleo is a mixer affiliate and his income is dependant on promoting mixers and he dislikes how mixers are deemed financial services so are required to licence up, to remain in operation. but here is the thing. but bitcoin being regarded as currency. bitcoin businesses need to follow financial laws associated with currency.
he/they can bitch and moan about how their favoured/promoted service should not be listed.. but they are. so they/he should think outside of the box, via:
a. wanting to lobby to get bitcoin as  whole recategorised as private property instead of currency
b. invent something not listed in laws. but achieves the same goal

this proposed legislation is not just about mixers..  but its not about individual fund holders, node users. he needs to think beyong the biased blog he read and actually think about the greater details that matter and are concerned

mixers have been under regulators radar for years. there is no stopping it. if he only cares about the function of de-tainting users funds "for privacy"(or more politely for him to get commission for suckering users into using them) he should seek out advice on creating a new option that is not described as "mixing" and does things differently

EG a merchant handling funds in exchange for goods is treated differently than a currency exchanger, so think outside of he box as to how to offer something that is not categorised as a MSB/MTS
