We're talking about two different things. The grandparent said that Assange hasn't had to make any retractions and hasn't published any false info. This is undeniably true.
They also said "like him or not". Not everyone likes the outcome of his leaks. Many do. Many like some, but not others. Regardless, he's had a major impact on politics based on very true information Wikileaks has made available to the public.
If the Ashley Madison password leakers were helping expose corruption in the government, I'm sure some would view them as folk heroes too.
