Interesting Mindset Change

So today I watched a video by this youtuber call Techlead who is a dud that has worked in Google and Facebook before, seems to be a big cock but a funny guy, i find his video and quirk sense of humor rly interesting. Then i chance upon his video giving coding interview tips, just nice ive been finding jobs and interviewing like mad recently, i find his interview experience as a Google interviewer really insightful and relatable to my recent interviews esp the one with Shopee where there were on site case interviews which can say is slightly similar to coding interviews.
So i sent the video to my hs frens grp and soon later someone replied me with another video of another youtuber's video pointing out on how Techlead is a fraud and trick ppl in buying his services and products. 5 mins into this video and looking at Techlead's videos again i realized that my perception has become sort of negative, and i starting to making up imaginary flaws in Techlead's video even tho nothing has changed for me. Then it got me thinking y is this so, partly annoyed at the fact that my fren just reply my video with a negative video without even checking both out and make their own evaluation. Also kinda annoyed at myself on how easily I am to be swinged by such negativity. If im not buying Techlead product or whatsoever what value does the negative video add here, absolutely nothing and it has effect on my mindset. Of course if i am buying i will do my own research and make decision. But as of now if i see value and entertainment in Techlead's video, I should not let this kind of thing affect me isnt it.
but again, the point of the negative video maker is to point out the aspects of techlead that does not concern me, so i should just ignore it maybe??
