Because they took the time to disclose the parts of their situation that supported the point they wanted to make (work at stripe, live in Ireland), but disregarded the parts they knew would discredit them a bit (PR for the company). Also, coming to their defense from a throw-away is a curious choice.
Fair enough, I should have looked before I added the snark - upvoted cause fun response. But the rest of my comment stands, I do think they selectively disclosed and working in PR would know they were doing so.
