Why are people saying this? From what I know, Jeremy Corbyn wanted to decriminalise the sex industry.

Criminalisation of the sex industry generally comes from the political right, not the left. It was the Conservative party in England that introduced all sorts of ridiculous laws on pornography in recent years. It was the DUP that spearheaded legislation to make payment for sex illegal in NI. Corbyn and McDonnell have both spoken about decriminalising the purchase of sex, much to the confusion of partisan feminists.
