before all the bitcoin forks were actually trying to creat a new coin. and actually contribute to the technology. you can look at Litecoin and its creator Charlee Lee for a good example of a good coin forked from bitcoin.
but this new wave of coins forking from bitcoin are just trying to make money. usually it is with the airdrop, mining and pump and dumps.
this bitcoin gold one choose to also premine the shit out of it before release too.
Forks can happen daily but if the chain doesn't last long it's not even worth mentioning.
Why do you expect a lot more Bitcoin forks? I believe it is better to make better cryptocurrency with improved technology from scratch. If you fork Bitcoin you already have 150 GB of blockchain. But of course making completely new currency for every little change is bad too.
Tha 1st of august fork was definitely not about making money, but more because different views of Bitcoin.
