Meh... They used to call it a scam until they realised 900 devs across 4 studios globally constantly releasing updates that are growing the game makes that argument look daft.
So they switched to calling it a tech demo, that's not entirely wrong but more wrong as time goes on, the number of "i was wrong about Star Citizen this is amazing" type videos is steadily growing, tho it still has plenty of sceptics, which is healthy IMO. $552,533,576 raised to date and 4,431,470 accounts it has a lot to live up to.
It even has two "Star" copy-cat games in development, Star Atlas which looks like its going to fail and Bethesda's Star Field which after 7 years of development sadly looks like its also in trouble, its incredibly complicated, its pushing way beyond all sorts of game dev boundaries.
