What might have happened had you waited until you were off the phone?
This reminds me of the last interaction I had on #lesswrong - I openly speculated about the UI of a system I didn't have access to, because I wanted to chat about it with people I generally respected. But some of those people just weren't in a good mood and lambasted me for not simply "googling it for the answer." Never mind that the answer isn't easily found, and never mind that that completely invalidates my whole reason for interpersonal interaction anyway...
