This comes down to the old question of ownership. The people/companies that own these films are trying to squeeze as much money as possible out of them. They remake or update them because they think that most won't go to see a re-released original version. I hate to see these classics butchered as well but I would also hate someone telling what I could or couldn't do with something I owned. The only way to really keep them from ruining these movies (IMHO) is to get people not go to them. Take the financial gain out of it.
