I guess the public has a diminished interest in youtube vlogging/streaming nowadays.
My favourite channels back in 2019-2021 receives 300k-600k with regular uploads (millions for good content) are now receiving less than 80k views. Some even stopped uploading. I randomly checked some YT channels and it’s the same thing. I guess this is because of post-Covid where people have more things to do and wanting to be outside, over-saturation and repetitive/boring content, etc.
I do not follow the channels you mentioned, im speaking generally. I guess the issue is both on the supply (repetitive/boring) and demand (decreased significantly compared to covid era). I don’t think it’s gonna come back to what it used to.
You mentioned the SPEED guy’s reason is lack of support and before that is the work behind the scenes - maybe it’s just not worth it for some to continue doing it.
I guess keeping YT channel will have to be as-you-want basis and accept that the hey days are gone.
