Looks like this is iProperty's retaliation to the recent PropertyGuru article stating they were No.1 in Indonesia:

I wish they included some meaningful data to prove their statement. It is a propaganda war without proper comparisons to evidence their claim as no.1 in Indonesia apart from having the most listings.
