Maybe, but wt can do whatever they legally like with their property same like everyone else can too.
This is true and I respect anyone's right, including the WTS, to protect their copyrighted material however we all know that it's a hammer to crack a nut. It says everything that the WTS, a global corporation with a reach into the lives of millions of people chooses to spend some of their vast resources in trying to stop a couple of home brew, amateur activists from using some of their publicly available content just because they can.
One may say "two wrongs don't make a right" but no one has actually proven a wrong has been committed. The WTS takes this path because it's easy for them and youtube is never going to question it.
It's petty bully boy tactics and will never stop the WTS being hoist on the petard of their own words in the long run.
