What are your thoughts on using platforms like IPFS or Filecoin for this purpose? They offer decentralized storage without the associated block space concerns of directly using Bitcoin.
using filecoin is not free though. and it only offers temporary storage. if you were using it directly, from what i understood is it's only free to retrieve data for the original uploader. everyone else has to pay for retrieval.
there are services built on top of filecoin but they cost a subscription fee aka similar to web hosting so you stop paying your site goes away. using ipfs directly would have the same issues. no one is going to "pin" all your terabytes of data for free.
so i don't think these 2 technologies would be affective.
