Invidious is just a frontend to Youtube like Teddit was a frontend for Reddit. It’s not federated, and Google can and will do everything in their power to make it suck. Just like how Reddit will now destroy Teddit next month.
Peertube is the federated option for video hosting/sharing. But of course, like everything else currently controlled by the centralized mega-corporations, there is a huge network effect hurdle that users need to overcome to get their content off of the user-hostile megacorporations (Youtube) and onto the federated alternatives (Peertube).
I see invidious/teddit/nitter/quetre/rimgo/scribe/libremdb as stop gap band-aids to temporarily give power back to the users, but in the end the owners of the content have full control over stopping these.
This is why it is so important that we promote federated networks like lemmy, mastadon, matrix, peertube, etc… Otherwise the entire internet will be a user-hostile cesspool.
