I...do not understand this take. Those names are their differentiating marks because most of them (not all, and TTI is more aggressive about this than most but their mark licensing is very long term) have existed forever and been aggregated together through different acquisitions.

SBD didn't invent DeWalt, they bought a company called DeWalt and expanded them to more tools.

What I mean is that corporation routinely operate on many different branding to segment the market, they might use the same parts or intentionally produce a lower quality product to not disrupt their higher margin, higher quality line.

I see so much effort spend on that kind of marketing (lying) and so little spend on improving the product, reducing the cost, increasing longevity, etc.

It’s everywhere, oven, fridge, tools, cars, etc.

At some point the confidence in the brand crumble and we just buy the cheapest chinese thing with a funny name.

IE: brand used to mean something
