I think self hosting may be cheaper for huge data volume stuff? Like I serve (legal) video, audio, audiobook, book, and photo content, it amounts to around 20TB of content. It cost me around... 1k in capital for all the components for it, most of which went to the harddrives? And according to the self hosting people on reddit I'll probably need to swap a drive every few years, around 150 bucks a pop. Beyond that though my only cost is electricity, for which I have no idea but our monthly electric bill total is like 80$/month anyway so I'm not stressed about it. Anyway I'm not paying in/out costs or costs for static hosting. Looking at hetzner's offerings it apears to be 536.58 euros/month for 10tb of storage? That's block storage on SSD, maybe they have cheaper HDD storage somewhere? Point is I think my server setup may have "paid for itself" (not that it makes me money) after one month. And that's for 38TB total of RAIDZ1 space, I'm only filling 20TB so far of it. In actually it's like 60 something TB of space lol I just wanted RAID so I could lose a drive. I've got plenty of room to grow and swap components as needed.
