May be brother someone has already aswered to your question. But I want to give my view because it warried me too.
As Allah has created evrything, i.e. the technology that they conduct too, this means that Allah also gave to good, i.e. muslims, to use this creation of Allah for good wills. Although they have srong information power in their hands and they use this for the sake of satan, the most Almaighty is Allah, and even when you look to such kind of videos to free your mind or get information what is really going on in this world, it's normal that you have doubts if's also not from satan or from real muslim, as our prophet (p.b.u.p) awared ummah time will come that fitna will be evrywhere.
For me after watching the videos (especially "arrivals") I understood that I could notice what really on this world by readin, applying Quran, thinking on it and analysisg evrything in the world by it before. After watching these videos and understunding this I''ll not watch such videos anymore and begin to live my life and my religion as Quran whan't it off us.
But anyhow this videos (especially "arrivals") helped me to come to this mind. Thats why I'm greatfull first to Allah and after to that guys for their efforts to enlight teir brothers.
Assalamu Aleykum va Rahmatullahi va Barakatuh.
