You can argue that you want to preach to people who are on youtube, that then becomes a reason to be present on youtube. But this is matrix.org -- their own site that they (matrix) control, and they choose to lead people to youtube (Google) from there.
To me it indicates either that they don't understand the problem, or that they don't care. Either way, it looks bad.
Be on youtube if you think you must, but keep your own site clean. Don't act like you are owned by Google.
It's about reaching non-tech-savvy people who are not sensitive to decentralization, opensource and free software.
Advertising only in the bubble of people who know it anyway makes little sense. Except that these people can also spread the word.
I'm on Twitter just to educate about secure messengers and alternatives.
@rumo, I think the point of @eliasr is that @matrix needs not use YouTube at all for video hosting and from non-tech-savvy people’s point of view there’s virtually no difference. Tech-savvy people would use an alternative front-end like Invidous or youtube-dl anyway. The organization can mirror those videos on YouTube for better reach from YouTube users though.
The answer is easy: put the original on peertube or wherever, and put a shorter version or a teaser on youtube, with a link to the rest. Give people a path toward discovering the approach to video sharing that doesn't take advantage of them.
Don't be satisfied slouching to youtube if you are supposed to be an organization with a vision! Give people what they want, reach them, and push things in the right direction! #privacy
