Actually, not everyone has been attacking him by pointing out his faithfulness.
I think he is putting too much emphasis on the poor (although we will see if he keeps this up in the coming months and years), and I think he is being very imprudent and taking unnecessary security risk like riding the bus instead of a bulletproof car, and worse yet, going into St. Peter’s square on foot.
If you ask me, this is asking for trouble, especially if he makes this a regular habit. He is not respecting his own life enough.
Perhaps he is leaving that up to God.
