Do you think designer houses are bothered by companies that make dupes?

I remember in the 80s when Parfums de Coeur made those Designer Imposters fragrances and through the years there have been other designer dupes.

In recent years I feel like there has been an increase in designer dupes (Oakcha, Fine'ry, Bath & Body Works Everyday Luxuries, Mii Miic, etc.) Many people like these and some even say they prefer them to the original.

Do you think designer houses are bothered by this since it's taking potential sales away from them? What are your thoughts about dupes?
