I am on the Dáil committee that questioned Facebook executives over shoddy practices, highlighted in a recent Channel 4 programme. I put a series of questions to them. They were slick and clever, but many questions remained without a clear or satisfactory answer, and in some cases facts presented to them were simply denied . You can listen to their answers on the Oireachtas web site via these links: https://bit.ly/2LLtUZu (go to the end of video); and here: https://bit.ly/2Mdx70i (see the start of the video).
