Agreed. But lets also give accuracy some due here. Pope Francis has removed many priests, bishops and Cardinals over this issue. He laicized Josef Wesolowski in 2014 and put him on trial in 2015 in front of the Vatican Tribunal. In 2014 again in his own backyard in Argentina he laicized Jose Mercau who was convicted and pled guilty to sex abuse charges. 

He has also done the same actions when it comes to bishops and cardinals such as defrocking in 2013 Luis Bambaren who was the former head of Perus Conference of Catholic Bishops and just recently his removal of Cardinal Mueller as the Vatican's doctrine chief which is significant because it was Mueller as head of the CDF who stonewalled a lot of the abuse commissions proposals. 

So Pope Francis deserves legitimate criticism on not issues such as not ending the Pontifical Secret or changing Canon Law on this issue of sex abuse. But saying he's trying to protect child rapists is not one of them.
