This applies to running small and medium business, but not to "inheriting" large chunks of [especially mining and extraction] industry.

There, mafia doesn't have any business commonly associated with them. Mafia does loans, racketeering and vice. Large industry isn't about any of those things. Maybe I'm wrong but I think you should not overextend the meaning of term "mafia".

Anyway, this does not answers the "fair" question. Oneself fairness is not direcly affected by people the person in question has to deal with. You still have to prove unfairness, "he was seen near where the mafia usually manifests" doesn't cut it.

You are arguing just for a purpose of arguing. I am not going to play that game. The way of doing big business in Russia involves bribes, corruption, ties to organized crime, cronyism, very close ties to the ruling class and government, and also Russian security apparatus. Also, the idea that a random "Russian Businessman" can just flash his money and be accepted as an investor in Silicon Valley should be in fact investigated by the FBI. We do not need to enrich "Russian Businessmen". We should be working with people from countries who are our close allies.

Does it make everyone who manages a high-profile international mining business unfair without trial? Because they are known to do the things you mentioned.

I'm not arguing just for a purpose of arguing. I'm trying to challenge your idea of "fair rules". If we would not find even one person in this subset who plays by "fair rules", (and you seem to imply there are indeed none), how do we know that "fair rules" exist? Who sets those?
