This is from a news article :
Huffman now takes issue with the third-party apps that are building a business on top of his own. “I didn’t know — and this is my fault — the extent that they were profiting off of our API. That these were not charities.”
I wonder which verb 'That these were not charities' serves as the object of?
I looked up 'that' in the M-W dictionary(conjunction 1b).
Or is the "That" in the quote this 'that'?
used as a function word to introduce an exclamatory clause expressing a strong emotion especially of surprise, sorrow, or indignation
that it should come to this!
