Adding my comment in the hopes it will inflate this thread's visibility.
I've noticed some people blaming Matthias for this which is silly. We all like to think we've got our security tight and locked but the truth is that, for almost all of us, it'll never be tested.
I found the same thing. I think it's one of two possibilities. Either they were
able to redirect his channel to their (completely separate) channel, in which case the upload date and view count would have been more organic, or they were able to replace his videos with theirs, leaving his video's view count and date-uploaded intact (although I find it hard to believe youtube's creator tools would allow for a complete change of video)
Matthias is the man behind the `panto-router`, a clever, pantograph-inspired woodworking router mount which went viral some years ago.
His YouTube credentials were stolen this morning and his videos are being replaced with crypto scam primer videos, as can be seen here: https://www.youtube.com/user/matthiaswandel
This situation is not only a loss to the DIY and engineering community but also poses an unfortunate risk to those who may fall prey to these scams, as his subscriber count now lends credence to their messaging.
I'm hoping someone from the Google's YouTube arm will come across this post.
