I knew a lot of people that liked it when I was in my 20s as it was a readily available step above your standard dry gins and wasn't really that much more expensive.
Gin is one of those spirits you generally taste pretty forward in a lot of drinks it goes in, so getting a slightly nicer one can make a load of difference.
As for why you don't see it as much these days, about a decade ago we had this kind of gin renaissance and loads of new really tasty and interesting, smaller batch gins started showing up. I'd bet a lot of the demographic that made up Bombay's market shifted into buying the craft gins instead
