You have to accept that when the thing you love becomes so popular, so part of everyday public life, and becomes so oversaturated with content, that it's bound to be appropriated for other uses, or bent to the will of certain individuals.
You can't hold onto it all. Take what you like, and leave what you don't. There's plenty to go around, and even the things you don't like may afford opportunities for product that otherwise wouldn't have a chance.
Every franchise evolves as it ages and passes through different hands. The Phantom Menace itself showed that Lucas himself had changed, and was changing the character of Star Wars.
The only purity is in the original, and everything subsequent risks muddying the water. The best output has been from those who honoured the character of original as close as they were able, but even then there's unavoidable instances where contemporary sensibilities emerge.
I feel the same way about Planet of the Apes. I love the original films (and series), and the ape designs. None of the later films came close to rivalling them, so I ignore them. They're not my apes.
