Facebook, Tesla paid millions for their domain names. Why not JioHotstar.com?

Mark Zuckerberg paid $700 to an engineering student from Kochi to buy a domain with his daughter’s name. Elon Musk waited over a decade and shelled out $11 million to buy Tesla.com. Facebook bought FB.com for $8.5 million from the American Farm Bureau in 2011. Why then did the buying and selling of JioHotstar.com go so horribly wrong for a Delhi techie?
