A well reasoned entreaty will always be better received than spam, angry threats, or boycotts that will only antagonize Lucas corp, other SW fans, and even the general public who will dismiss us as a bunch of whiny fanboys.
I've already written my letter to Lucas and while I don't expect a response (or it even reaching Lucas) I hope whoever does read it will get the notion that cherishing the originals is something that benefits everyone. And if they receive consistent reminders, the idea may take hold that this is something that everyone will want. After all, it's about our collective art and culture. Once people start believeing that it is a positive idea to preserve the originals along side with all the new SE/UE versions, Lucas may very well change his mind.
It will take time. There is still some venomous resistence out there, and fans who enjoy bickering amongst themselves too much. But if we can spread this 'new' idea and get everyone behind us on loving all of Star Wars New AND OLD, then who knows?
I hope others will join me to convince Lucas et al. May the force be with us
