I am surprised you think that. Considering busy.org uses IPFS for images to my knowledge. IPFS is a lot more efficient than traditional system, especially when talking about gateway/local node caching. A lot less usage on main servers. There is a few issues with IPFS regarding resource usage, this is fixed with changing settings. If a dapp had end users storing files/images, it wouldnt matter what the devs are doing to keep up the platform because the structure is made of community nodes.
