حالا بازم کسی هست که ادعا کنه دانلود فیلم از یوتیوب توسط ابزارها و سایتهای دیگری که برای اینکار ساخته شده، بدون اجازه رسمی یوتیوب قانونی هست؟!
ضمنا تمام کلیپ های یوتیوب تحت کپی رایت هستن. کپی رایت متعلق به مالک اولیهء اون کلیپ هست، که بر طبق موارد این قرارداد، به یوتیوب هم این حق رو واگذار میکنه که فایل مورد نظر رو تحت شرایطی که یوتیوب تعیین کرده (یعنی موارد بالا) استفاده کنه و به دیگران ارائه بده.
تنها زمانی شما میتونید یک کلیپ رو دانلود کنید که اجازهء صریح از مالک واقعی اون کلیپ داشته باشید. تازه اون زمان هم شما نمیتونید اینکار رو با استفاده از ابزارها و سایتهایی که برای دانلود مستقیم از یوتیوب ایجاد شدن اما اجازهء رسمی از طرف یوتیوب ندارن انجام بدید، چون شرایط سرویس یوتیوب رو با اینکار نقض میکنید.
