On Reddit people often ask me this question, the answer is no !
RYTM doesn't block ads directly, it's just a workaround.
In short, I'm calling the video previews, not the videos themselves. YouTube offers this feature to display videos on blogs or in certain apps, like McDonald's, where you normally don't see ads.
I also didn't recreate YouTube, I created a player with different features than the official app. I was careful not to violate the terms and conditions of use, and in fact, the app has been online for over two years now.
So enjoy, I did this with 🫀
