I dont know how people would switch off youtube. Youtube would need to shoot itself in the head or even a chance of people leaving the platform. Maybe creators could unionize or a new form of media could dethrone it.

When I tried Odysee I also did the same. I subscribed and viewed the videos on odysee but would pause and watch on youtube to save odysee bandwith and ensure that the creators I like that are pretty small wouldnt be hurt.
