> How are these DRM schemes actually being defeated? Stripping the more advanced forms of DRM usually relies on compromised device keys which can and will be revoked if it becomes known that they've leaked, so the details are deliberately kept very quiet. If you've ever experienced a device suddenly losing the ability to play 4K Netflix, it may have been because its keys were revoked.
