You are wrong. I don't know what you researched but July 15th, 2024, the government implemented a new 60 day visa exempt. For all of the countries shown in the image above, if you arrive without a visa, you will receive 60 days on entry. You can also apply one time for a 30 day extension, giving 90 days total.
Before July 15th, it was indeed 30 days. But it had also been changed many times before that due to other promotions by the government, most often to 45 days.
