While there are men who are going to "Thai dating agencies" and
actual Thai dating agencies, many are also just Swedes going on holiday or going to another country for work, meeting a Thai woman or another women from a country that isn't, bluntly, infected with batshit feminism, and starting a relationship which can sometimes lead to marriage or at least their moving to Sweden/vice-versa.
This takes them off the table for Grunhilda the Feminist Swede, which is why they're starting to panic.
Also, Thai women just happen to make up a large majority, but they're not
all Thai; they're also not all "sex workers" and mail-order brides, too.
Men like women who aren't masculine and batshit insane, who would have thought it?
