I'm not sure anyone could be shocked at what happens in Saudi Arabia, their dealings have been well known for ages by Amnesty International, US Dept of State etc. I think a more plausible explanation is your first point that they love Saudi money and they can ignore the human rights abuses as long as they stay suitably low-key and rumour-based. As soon as they go onto the worldwide news, these same people suddenly feign ignorance and walk slowly backwards from their deals.
