Crypto isn't morality, but the radical free market structure in this new environment will eventually lead to moral behaviour through the laws of behavioural incentives.
There are huge incentives to capitalise on ignorance, however these actors won't be around for long. Because where ever there is an inefficiency, there is incentives to counter them. Investing blindly in scams with devs with no reputation or even completely nameless actors is being punished while investing in well 
vetted projects with realistic promises and a solid model are rewarded. So there is a behavioural shift occurring and there is a market of trust being built.
The scams will eventually diminish to a minimum and thats also when mass adoption is going to happen. Instead of capitalising on peoples ignorance by scamming them, people will do so by providing a reputational platform (for a fee of course). Like gateways for the masses.

I don't know how far away we are, but we are definitely moving in that direction.
