Why dose YouTube do this now

[Plasma Gamer]

ok so we have youtube search right all good but now and we also have a channel based search witch is great but i noticed the other when i searched for some thing on this youtube channel that it showed videos from other channels WHY

like below i did this to show it easier but you may see the first 2 videos are ltt ones but then it shows videos from other channels now i know ltt did not make mc videos but youtube used to shot you video kinda like it or just a few video but why give me other videos from other channels in channel only search

Youtube wants you on the platfor for as long as they can to show you more ads. The algorithm recognises that you like minecraft videos so they suggest those to you

I thought I was going crazy. It is SO damn annoying isn't it? I was like WTF WHY are you showing me stuff that is NOT what I searched for.
