I've always thought the fiduciary duty argument was silly (and I'm not HN :), so I agree with you there, but that doesn't change the broader point - when you sell a company, it is no longer yours, and the interests and politics of a large corp with public shareholders and revenue targets are not those of a smaller acquisition.
I wasn't trying to challenge the broader point. I was trying to challenge the specific claim that some folks are making that Facebook Must ruin Oculus because balance sheet, which is nonsense. Although on re reading your comment I can see I replied too soon and you are not one of those.
