'they dish out even more' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'join chorus of criticism when' is the wordplay.
'join' means one lot of letters go next to another.
'chorus of criticism' becomes 'pile' (I can't justify this - if you can you should believe this answer much more).
'when' becomes 'on' (I've seen this in other clues).
'pile'+'on' is 'PILE ON'.

Can you help me to learn more?

I've seen this clue in The Irish Times.
