In the least sarcastic tone, who cares. The best floats to the top, so if other brands are copying ideas from other guys, that works out better for the consumer.
In the short term it sucks for the biz that did the r&d, they will recoup some money form first to market and brand buyers, but they will learn they need to innovate more or figure a way to lower r&d costs. Just a big cycle.
I think right now in companies are struggling with first to market , product test, and new products. No one wants the same model for a year and they don't seem to invest enough testing befor release.
