I found that thread while reading a reddit post https://www.reddit.com/r/Bitcoin/comments/1qance/question_charity_helping_in_the_philippines_that/

I think there is no Philippine charity organization that accepts bitcoin directly. It will have to go though a custodial service called Coins.Ph from this article https://bitpinas.com/cryptocurrency/donate-using-bitcoin/

The process may look like this
- Create Coins.Ph account
- Deposit BTC
- Donate BTC
- Coins.Ph converts BTC to Philippine Peso then deposit to the charity account
