It’s pretty easy to learn how fidelity and others make money on fee-free index funds. Perhaps something to look into before accusing them of committing a crime.
Considering someone or some activity to be criminal, and accusing them of being a criminal, are two completely different things.
I consider most financial institutions to be criminal because it is always their clear intention to circumvent the spirit of the law as closely as possible. The intention is to reap the benefits of breaking the law, without the risk of consequence. When the pitchforks come, these are going to be the criminals being chased down the street.
By the same token, I do not consider a parent who writes a bad check for groceries to be a criminal.
The client generally saves money in the PFOF situation. They benefit, their broker benefits, and the market maker they deal with benefits. The only loser is the abstract rest of the market being able to get fewer penny shavings.
What in particular do you see as against the spirit of the law?
