Saying "everyone does it" doesn't make it legal or right.
Going after Amazon and winning a ruling against is a good first step in eliminating these exploitive practices everywhere.
Which because they have gotten away with it for so long, everyone else has been copying (or well I guess this has been going on for decades in various forms) them.
Ex, netflix, which has decided to pop up a 'we noticed there are people who don't live with you using your account, click here to pay us another $9/month' every time it starts on my TV, presumably because my underage child, who legally lives with me, uses it on her phone when she is away at school for 5 months a year.
And then when someone clicked the default pay us button, I was unable to figure out how to remove the charge without actually calling and telling them I was canceling after 20+ years. (the whole extra member thing wasn't showing up in the web ui, no idea why, maybe its because of the TV clicking process).
