Youtube is one of the most valuable educational resources online. Often you can find links to other resources from helpful videos on youtube. A big part of this is because youtube has decades now of content on a huge variety of topics and unless someone is able to copy that archive of content I dont see myself switching to any other comparable service like nebula. The whole premise that allowed youtube to be an invaluable archive of tutorials and sources in the first place is that it is free to use and free to host on.
I also dont ever see myself paying for youtube or willingly not using an ad-blocker. If there is a creator I feel is particularly valuable to me I will consider signing up for their patreon but I dont feel its any of googles business who I choose to monetarily support.
