> Your description is not accurate for my state, California, there are clear tiers of ebikes with regulations on when and where they can go, with very clear explanation at purchase, and no weird marketing like you're talking about. I've tried to go buy them, I have experienced the lectures!
The people buying the hackable e-bikes aren't walking down to their neighborhood e-bike store and paying full retail.
It's an internet phenomenon. They're ordering them online. There are subreddits where you can go and figure out which ones to buy that can be easily hacked or modified.
There are companies addressing this demand by making bikes that are technically capped to a specific tier of performance when sold, but any kid with the internet can find the instructions to "unlock" it to remove all of the limits and use the full power of the bike, not have to pedal, and so on.
