According to Danny, some of the girls he invited over for himself to Antony's house, ended up getting hit on by Anthony. Right in front of Danny openly disrespecting him and showing no concern for him whatsoever. And Anthony once taunted Danny over the phone for stealing one of Danny's girlfriends away from him. A phone message that we actually still have. So one of the reasons Anthony was friends with Danny was literally just to steal his girlfriend, and not because he actually cared about Danny or had any some sort of camaraderie with him. Anthony never cared about Danny at all and threw him to the curb like he does with everyone else. Yet Opie for wanting to just relax with his family is the real monster?
Danny also once was allowed to invite a friend over to Anthon'y house for a party. And the friend proceeded to case Anthony's house. Wait for the party to start. And when the guests were all distracted and partying, then proceeded to try to rob Anthony's guests of their money and valuables by going through their purses and bags. This person was caught but Anthony sheepishly and meekly let the person go despite him stealing a few hundreds dollars from people. And didn't search the person nor call the police. These are the kind of people Danny wanted to introduce to Opie and his family.
Danny was fired from Sirius-XM for putting his feet on up Scott Greenstein's desk. Scott called him in to tell him not to bring a pornstar to some Sirius event and Danny yawned in his face and put his feet up on Scott's desk to mock him. Scott sent out a mass email (or ass email as Jimmy once said) which contained the phrase "I have never felt more disrespected in my life" and had Danny fired that day. Danny denies that this ever happened. Anthony didn't back Danny to management though when he was fired and wouldn't risk his job for Danny.
After Danny was fired by Sirius he was then hired by Lazlow of Rockstar Games as a favor to O&A and more specifically Anthony who begged Lazlow to get Danny a job. Danny did not get the job on his own it was because of his association with both Opie and Anthony that got him into Rockstar Games. Danny will also deny this and act like him being a glorified intern at Sirius somehow made him a highly desirable hire for a prominent video game and entertainment company. His job was to take screenshots of the game. He would eventually be fired from Rockstar Games and will of course claim he did nothing wrong. And then he tried too leak news of Read Dead Redemption 2 to the internet early out of total disloyalty and betrayal and damage Rockstar's business. Causing him to not be able to get a job in entertainment anywhere as his name and resume are worth nothing.
I still find it funny that Danny wanted to party with Opie. Party with his boss. Imagine the insanity of being an extra on a movie set and playing Stormtrooper #35 and then crying about how George Lucas didn't invite you to his house to party with you. "Yeah I worked as a caterer for Mission Impossible 2 and 3, and Tom Cruise never invited me to his house, what a piece of shit!".
Danny knew that Anthony was a pedophile and stood by him for years. Yet hates Opie? For not partying with him?
