> With more fiber being laid every day, increasing wireless deployments, and technologies like AirGig in the horizon, is Starlink launching into a shrinking market?

What you are describing sounds like a rapidly expanding market, not a shrinking market, though, right?

> Further, as SpaceX is having trouble raising the needed funds, is this launch simply a fundraising exercise?

What do you mean? SpaceX is not having trouble raising their needed funds. Do you have a citation for that? This is the first I'd be hearing of it and would be surprised. Also, needed for what? Are you referring to Mars colonization?

> is this launch simply a fundraising exercise?

This also doesn't make any sense. This launch is a groundbreaking event that begins a 12,000 satellite network deployment. This is a very cost-intensive thing and not exactly a 'fund raising exercise'; it's intended to provide early service to internet customers.
