Even the best content of the Daily Slice is rather controversial with its stances and aggressive language. Beyond that they do have specific things that really make them distasteful to a good number of readers - but are also the reason it endeared itself to others.
Doxxing
The Slice has on multiple - though rare - occasions revealed, or attempted to reveal, the secret identity of heroes and villains. They have been in and out of court on this issue arguing that a superhero is a public figure just as any celebrity, and thus they have no reasonable expectation of privacy including their civilian identities. Opponents to the practice have pointed out that this can put them and their loved ones in danger, but the Slice has argued that the practice of superhero vigilantism does this on its own.
So far the only major change has been that anyone employed by A.E.G.I.S. cannot have their identity leaked. It is considered similar to leaking the identity of spies in foreign countries or undercover officers.
Melongate
When the slice was revealed to be a watermelon, rather than a pizza, readers protested leading the the Editor-in-Chief to make a scathing public reply. See the Melongate Scandal for more information.
Responsibility Dodging
After a string of lawsuits and controversies the Daily Slice started adding a footnote to all web pages and physical copies that eschewed responsibility of any published article, decrying them as opinions of the writers themselves. This move has been praised by supporters as honesty that's uncharacteristic of other news sources, while detractors said it's basically admitting what they publish is little more than fiction. Additionally, many article writers have begun to use pseudonyms or pen names and the Slice claims they also don't know the true identity. This makes all parties of the paper technically blameless. They are currently in long, ongoing court proceedings defending this practice.
