Maybe, but on the other hand I don't really judge someone who does essentially the same thing without money being explicitely involved.
I have some acquaintances who are rather unpopular with girls here, who went on vacation to Asia (and I don't mean Korea or Japan, I mean China, Vietnam, Thailand...) and come back with girlfriends and plans of marriage. One of them the plan fell through as the girl found another western guy to marry, the other did go through with it, and the girl divorced him as soon as she got her citizenship. But in both cases, they didn't have to pay for it.
I guess part of it comes down to naïveté. It's hard to ignore the hard transactional nature of the relationship if money is directly involved, while the guys who don't pay for a foreign bride can wish, and delude themselves, into thinking there's genuine emotion involved.
Although there could be a cultural aspect to it. Asian cultures do openly consider the lifestyle a husband can afford his family as points of attraction, whereas it's considered unsightly and taboo in the West (not that it doesn't happen, but it's kept hypocritically hidden, doing it openly usually opens a girl to accusations of "gold-digging").
