Honestly, people have been ringing warning bells for a while regarding how Amazon facilitates illegal behavior, including:
Products like this whose purpose is obviously got illegal purposes and even described as such
Counterfeit/knockoff goods
Unsafe and/or not adhering to legal regulations in the country which they are being sold (sometimes often faking the certification logos)
As somebody who has dealt with the latter two, I hope this lawsuit puts on enough hurt and/or spawns similar suits so that Amazon cleans their shit up. It’s enough advantage that they don’t need to stock local stores without them being able to constantly thumb their nose at the regulations actual B&M stores need to adhere to
