Nah, let’s not go this far. Might be true for some AmazonBasics product categories, but I have a specific example where this is just not true.
Their AmazonBasics monitor arms are manufactured by Ergotron (aka one of the most reputable and best monitor arm brands out there). I have both AmazonBasics and Ergotron arms (purchased from their official website), and it is clear as day that they are nearly the exact same product.
I purchased the AmazonBasics arms back in 2016, and they still serve me great to this day, surviving 2 moves between west-east coast and many more local moves.
You can call this anecdata, but both AmazonBasics monitor arms and Ergotron ones have excellent reputation.
