This is not really true. I mean, yes anyone "can fork it" but that is just as valid as me saying anyone can run a code.

Well, there's a group of people, small by comparison to the rest of crypto users, with enough knowledge to clone repositories and and fork blockchains. It's true that these developers can fork anything they want, granted if they deemed it worth to do.

But, this does not mean that the fork would have any success or that the cost of forking a blockchain would be offset by the success of the forked project. In other words, it may cost someone too much time and money to setup nodes, communities, pay for listings on exchanges, and such, a lot more than that person or group of people could extract by then selling the tokens to enthused users.

Yes, there's a number of effective scams out there, effective enough to make this a "business model", but to think this is easy to do, it's to be ignorant of the gargantuan task of getting this off the ground.
