It's made by Frontier Development who I consider more than an indie developer but still not huge like EA Ubi etc. I rate them on quality since I don't know what devs are and aren't indie.
You have to distinguish between Developers (The ones actually designing and coding the game) and Publishers (The ones who fund the devellopers and do the sales and marketing stuff).
EA and Ubisoft are both Publishers.
Bioware and Frontier Developments are Developers.
Bioware is under contract of it's publisher EA - that is where they get their payment and game budgets from.
Frontier Development is an "indie" developer, because it doesn't depend on a big publisher to get their funding and do the marketing.
It used crowdfunding (via kickstarter.com) to get the money and they do the marketing by themselves.
The relationship between developer and publisher is similar to a band and its record label.
The label enables the band to record their music, does the advertisement, presses the CDs and sells them. In return a big part of the money from the sales goes to the label instead of the band. If the band has access to money to be able to do all that by itself or hired people, they do not need a label and can use the revenue from the CD sales by themselves without having to adhere to a contract. That all is very simplified, but roughly that's how it goes.
Now you might ask why so many developers let themself bind to a big publisher if they could do it with crowdfunding instead?
There are three big reasons:
1. Crowdfunding is unreliable. You might think your Idea is great, the general public might not be persuaded that easily and your project might already fail due to lack of funds.
2. If you want to make a game of a certain series, you're not allowed to do so, if a publisher or someone else holds the right to that series, else you'll be sued to kingdom come.
3. Crowdfunding can accomplish a lot if the public likes your idea, but there's no budged like the budged of a big publisher. Mass Effect is a prime example. All those fancy cutscenes and voice actors - that cost a crapload of money. That is why indie games mostly have less graphic fidelity and textbased storytelling. I rarely mind that "oldschool" kind of stuff, but it is another experience to play the ME-Series compared to - say Shadowrun Returns - still a great game, no question, but just imagine what it could have been, presentation wise, if a big publisher was behind it.
Sorry for playing the big smartass here, but that is a topic every gamer should know about in my opinion.
