The reason for this is because consumers will ultimatly act rationally and in their own best interest
Rational consumers will act rationally, but the fact that we have literally tens of thousands of complete scam tokens and coins that people continue to lose their money on, and we have 100% proven scam exchanges like YoBit still operating, proves that this space is
filled with irrational users. If any service thinks they can largely get away with doing something which will harm their user base in order to make themselves more money, then they will absolutely do that. Robinhood is a great example. Other examples which spring immediately to mind are Coinbase selling customer data without users' knowledge or consent, Binance tricking newbies in to buying some fake bitcoin token on their centralized scamchains rather than actual bitcoin, and Wasabi implementing censorship in their wallet. Plenty of people don't even know these things are happening, let alone actually care about them.
People use YoBit largely for one of two reasons. One, because they are not aware they are a likely scam exchange. Two, because YoBit does not scam all their customers, and their scam is one such that it is possible that
some of their customers will make money while participating in their scams -- in other words, customers are gambling.
You mention that some customers do not care that companies are doing what you believe are negative actions. None of what you describe removes
all value from the products the various companies offer. The free market will handle these negative behaviors.
Companies will offer what makes them the biggest profit.
Consumers will usually buy what appears to get them the best deal for the money.
I think your bolded statement agrees with my statement. If a consumer is not going to buy what does not get them the best value for their money, the company is going to be unable to realize sales from a product with a bad value.
