Cloud Repatriation, anyone else moving from cloud to your own hardware in light of costs and security of your data?

This was awhile back I had some drinks with ex coworker who at the time was mulling over the idea and asked if I wanted to come on board to help. The amount they spent on just backup itself even with dedupe, to the same regions was probably over $10 /TB? I’m not sure I had a few too many drinks since it was free on someone else’s company but someone else pinged about this today and I remembered talking about this

I declined but once in a blue moon I’ll attend a tech meetup in my city and I’m hearing more mullings about this though I’m not sure anyone has actually done it.
