Sanity Content Lake - Their data, not yours

I have an issue with the Sanity Content Lake.

The Sanity Content Lake is where your content is stored and accessed. It runs in the cloud and is fully managed by us.

What I read: your data is ours, and we control it.

You want to keep the data in your own server you say? Not possible. Do people want it? Yes they do.

Why isn't it possible? Would only be guessing from my side, but data is quite valuable isn't it? And Sanity has investors and surely ambitional growth plans. I can only imagine data ownership being an important factor.

Call me old fashioned, but I'd rather choose where to store my data myself, however fancy and convenient the "lake" is.
