They tested it and decided against it because the economics didn't work out. That's how things are supposed to go. Data centers in space will work out or not. They have some engineering hurdles to get over and some bigger economic hurdles. If they succeed, great! If not, we've learned, and can turn to the next idea.

We don't need to proclaim them a success or a failure yet. I don't think they'll be sensible economically for at least several decades, but I welcome the research.
