It is not intrinsically bad to modify an idea, it is bad to take an idea that is meant to improve people lives, then twist it so that instead its concepts are used so that corporations can make more money, while pretending it still improves the people lives.
Every idea can be interpreted in this light. In fact, a modified version of this argument is often used by conservatives opposing women in the workforce.
“Well sure, womens rights might be good, but you see, the feminists twisted a good message and now they use it to push women away from motherhood and into corporations so the corporations make more profit and sell them more things”
Is it also bad when feminists encourage womens participation in the workforce?
