A big company can stall a copyright lawsuit for as long as it wants. Small companies cannot win against Amazon in court.

And CVS follows the formula of name brand OTC drugs down to the very ingrediant to make house brands. You can’t copyright a shirt measurement.
And before you call me an “Amazon shill”. I got PIPed from Amazon less than two months ago. I’m the last person who has any love for Amazon. Honestly I don’t have any feeling either way. It was just my 8th job over 25 years, they gave me a nice check and I had a comparable offer within two weeks.
Like with the sears example, large 'mall' like organizations do outright steal designs and stonewall the original copyright holder.
A random housebrand does not have access to Amazon's statistics, logistics or reach. Amazon is looking at stats that they hide from their providers, to choose who to copy, then out-price the original seller. (Due to inhouse logistics)
They are not even remotely the same thing.
And Walmart sells a lot more than Amazon.
You don’t think that every store knows how to undercut other products in its own store with house brands?
