Spitz has always antagonised the community since the first Helldivers on Discord and at times acted like a complete prick. He was always going to be on thin ice with a game a popular as HD2 and everything anyone associated with it will get reposted and scrutinised. It a bad look for ArrowHead and an even bigger bad look for Sony.
The posts he made on the official discord about using fake email addresses or a vpn to link your steam account to psn in a effort to down play the drama probably didn't go down very well as they are clear violations of the psn terms of service.
