I have a question about the combination "criticized from" in these news articles:
1. But with her seven-year term set to expire in July, Justice Poritz has been harshly criticized from both ends of the political spectrum in recent months.
He's been criticized from the left for failing to focus on the economic causes of inequality.
The meaning probably wouldn't change too much if "criticized from" is replaced with "criticized by". Maybe it is just a journalistic style.
But for native speakers, does "from" convey some hidden meanings that "by" lacks?
