They do this to increase viewership, simple as that. I watch LTT videos because I know they’re of a high quality, each and every one (maybe aside from the weird iPhone rant one lol). It makes complete business sense for Linus to present his thumbnails and video names in such a way and with the quality of his videos I don’t even need to see the title or the thumbnail, I’ll watch it regardless.
If you guys have such a problem with his videos then I’d suggest simply moving on and viewing other content, nobody’s forcing you to watch anything you don’t enjoy.
