I don't have twitter, so I'll leave my response here:
When the video goes on the bottom corner of my screen, it gives me the feeling that I'm kind of forced to watch this. Even worse, I don't think it's useful because:
Whenever I'm interessed by the video's content, I'll watch it or put it on fullscreen; If I'm not, I'll just continue my navigation. I won't change my mind after several seconds of "harassment" on my screen and ears.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
