Why Indian celebrities don't open Youtube channel??

I am regular Youtube viewer and i follow few youtube stars regularly. I wonder why some bollywood/television celebrities do not open their own channels. Many HW celebrities have channels. Recently while watching Superwoman/Lilly Singh's video, Will Smith collabed with her and he opened his own channel. I am not saying Alia Deepika Kareena Priyanka Katrina etc to open youtube channel. Some less popular/ struggling actors can do that. Look how popular those logan paul & jake pauls are. I can see actors like Arora sisters, Ameesha etc can do these and earn a lot coz regardless of what they do, they will still get millions of views. There's argument about how struggling actors enter prostitution business to earn money. Some of the tv celebs have crazy following, they can open channel cz after 2/3 shows their shelf gets over. Recently read, how Juhi Parmar and Sachin got separated due to difficult times. And there's lots of blinds about lack of opportunity or work for Shaan Sonu n other. But i think they can open channel, compose songs or skits to earn money and fame. Look how popular Lilly Singh is.. She gets invited in so many big events and has so many connection.. She created the niche for herself.. She didnt wait for opportunity.. Liza Koshy also got lots of fame for that..We call celebs wanna be and so.. But look many popular YT like logans, pons, abd others are not making any oscar worthy videos.. They earn huge money by selling march. I am glad there's many channels like Ashish, Sahil and few more. IMany celebs create publicity stunt but hardly they get work due to their stunt but media is getting benefitted due to their stunt. I think many indian celebs would get success in YT. They can blog, make skits, make up tutorials, BTS bw parties and lots more.. Do you think its their ego to not try YT coz many tv celebs leave their shows for movies or to earn more fame but fails most of the time due to favoritism in bw. Coz i enjoy and respect few YT stars more than Bw/hw actors..
