shitcoin = racket. scam. trick.
luke already had his bulk asic purchase plan ready for every one of the hash functions he put in the "random selection" that landed on blake2b. i would hope you are educated enough or did your homework to know that Sia uses this hash function and there is a live, active market for asics that do this hash function. so it makes an easy win to mine a majority of early blocks on it and then trickle-dump them on retail. all without looking bad, but making a profit on gullible people.
someone with over 7 years experience working with bitcoin knows the difficulty adjustment is going to be a big problem for forks. so they can plan it easily "oh, we are dropping the difficulty to X because there will be less hashpower" and they know they have 50% of that right out of the gate.
