"Additional tax applies to income derived from Chilean sources by individuals or entities not domiciled or resident in Chile, where the income is available from Chile to the person residing abroad. Dividends, withdrawals and / or repatriation of profits by corporations, partnerships or permanent establishments of foreign companies are taxed at the general rate of 35% additional tax."

Note the word "additional". So, this implies after regular corporate taxes are applied.

So, you form a corp in Chile under this program, then you leave after 6 months. You're no longer a resident of chile. You want to take your companies profits out of chile, then this tax would be applied. Depending on the industry, and the corporate tax rate, it looks like it could be as much as %52! (%35 plus corporate taxes.)

This is actually one of the key indicators of a regime that you should be wary of. Currency controls are what governments impose when they find their policies are driving businesses out of the country. I'm not saying that is the situation in chile, I'm just saying that this is the historical role these kinds of taxes have played.

This tax, and the others I mentioned are confirmed by the links you gave, so it is wrong to claim they are "uninformed speculation". Turns out I was quite well informed!
