How do we replace YouTube?

Hi, my post is focusing specifically on YouTube since I observed the following categories have less intrusive solutions or privacy focused solutions, even if they are paid:

• Operating Systems (Linux, for example)
• Instant Messaging (Element, for example)
• Community Messaging (Revolt, for example)
• E-Mail (Proton, for example)
• Office (libreoffice, for example)
• Password Managers (Bitwarden, for example)

However, how do we distribute videos and watch them without data collection? I am NOT asking how do I use a privacy-focused front-end for YouTube, by the way, I am aware they exist.

I am wondering how we obtain a FOSS solution to something super critical such as YouTube. It is critical since it contains a lot of educational content (I'd wager more than any other platform), and arguably the most informative platform, despite having to filter through a lot of trash. During COVID, we even saw lecturers from universities upload their content on YouTube and telling students to watch those lectures. (I have first-hand experience with this at a respectable university).

I refuse to accept that there is nothing we can do about it.
