YouTube serves probably dozens of formats/bitrates, and has spent years tweaking how it ingests, transcodes, and serves videos. Adding in-stream ads might have been a bigger engineering task in that environment. Depending on the percentage of users/viewers avoiding ads, it might not have been worth the return.
As I know they transcode every uploaded video to their preferred format. They could use the same infrastructure for the ads. But maybe it’s really too expensive.
You are correct, which goes into the cost category of doing a stream stitched integration. Also, when I left said ad server in 2016, I think I recall HLS streaming primarily supported by Apple devices. Devices like Roku’s (don’t quote me on that) didn’t support it at the time so a lot of companies looked at where the majority of their streaming was occurring and decided it wasn’t worth the hit.
