Since there were few reliable citations available of actual quotes of the reformers, the council of Trent condemned propositions that were heretical but which may not have actually been held by actual reformers. They did not condemn anyone by name either. So it would be more proper to say the anathemas were amed at propositions, and not necessarily at the particular propositions held by any reformer.
Hilaire Belloc wrote about the politics and economics of the Reformation in a book called 'How the Reformation Happened'.

Polemics won the day. And it's still alive today, thriving even.
Here are two current views of the selling of indulgences:
SELLING INDULGENCES. In the dark ages, when Papacy held control of men's consciences and few dared to think, one method which she practiced to supply herself with money was the sale of indulgences. The indulgence was a permission to sin and yet be free from its consequences.
SELLING INDULGENCES. The Pope (or the bishops in Germany) did not approve of the "selling of indulgences"... there were abuses that priests and bishops did not correct and check. However, the Church has never taught that money remits temporal punishment for sin.
We haven't progressed very far. We still argue and don't listen and don't actually communicate a bit. And we like it. And so it goes.
