Not sure what hullabaloo -- they do provide a bunch of services to Canadian institutions (including Libraries and Archives Canada) and they perform physical services like book scanning and in the last few years I believe they are the parent organization for the physical Canadian datacentre _somewhere in BC_.

For my work, I worked in their Archiving & Data Services department, on https://archive-it.org/ -- I didn't know this before I joined, but Internet Archive offers various for-pay services to other cultural institutions, mostly around archiving their stuff or white-labelling playback of archives.

For example https://webarchiveweb.bac-lac.canada.ca/ (the Government of Canada's own Internet Archive) is actually outsourced to ADS within Internet Archive.

On one hand this is neat, as IA have expertise around this, but on the other hand (as a Canadian) I don't like that it's not actually sovereign and that it looks like it's run by our government but that it's not. Tradeoffs, I guess.
