Hello Mark,
Thank you for your e-mail.
As you point out even streamed content can be copied (through the
use of "stream rippers", etc.), but streaming is a good-faith effort
to prevent the unauthorized copying of content.
When it comes to protecting the content, streaming is preferable to
downloading because:
1.) stealing streamed content requires an explicit act
on the part of the malicious user, whereas
2.) downloading content, by definition, places a copy of the
content on the user's machine, thus violating our commitment
not to distribute the material
We are designing our disseminator to display copyright and fair use
language, thus we are acting with due diligence and it is the malicious
user who is breaking the law.
Regards,
Joe
