It would be true if the reason for using this technology is to create a new type of financial system without having to restrict previous central systems.
What is happening now is the shift from a new system of transactions to new speculative systems, all trying to create more currencies for unknown reasons.
Well, in any new system devised, there'd always be crooks who will try to copy the said system and make some money off of it. The reasons aren't unknown IMO, only deviates a little from the original thought (which is making money out of nothing) while sounding as if these new systems have all the answers to the world's problem. They are all the same tbh, and no, it doesn't include bitcoin (and that's not bring bias).
Also, trying to create an infinite number of shitcoins reduces the likelihood of decentralization.
True, especially if the main goal is money. As I've said, they are all but deviations from the original system, having the same goal for profit.
