As chief executive Jason King watched on in Manly's press conference room, Fogarty revealed his disappointment that the man who had convinced him to move from Canberra had been axed only three games into the new season.
The veteran has made a decent start to life at the Sea Eagles despite the team's winless opening month, but said the playing group needed to shoulder blame for Seibold's demise.
"It's pretty disappointing that we let our coach down and now ultimately he's not here anymore," Fogarty said.
"(It's) above my pay grade, but if I was the owner of an organisation, I'd like to see him have an opportunity to turn it around.
"He's not out there missing tackles or knocking the ball on and stuff like that."
The Sea Eagles are no strangers to recovering from slow starts to the season.
The club lost their first four games in 2021, only to surge into a preliminary final on the back of Tom Trbojevic's career-best form.
"We still have 21 games to go to turn our season around. I thought to be sacked after three is pretty harsh," Fogarty said.
"He was the reason that I joined the club. Unfortunately three games haven't gone our way and he's had to wear that.
"We can't control that. It is disappointing from my end because he was the one that got me here, but life goes on, doesn't it?"
Fogarty has reached out to check on Seibold, only after first getting in contact with the 51-year-old's wife to determine whether he would appreciate a message.
After King told Trbojevic on Friday that Seibold had been fired, the Sea Eagles captain called his former coach to apologise for the way his tenure had ended.
Seibold had effectively been three games into a two-year contract extension, having signed on for the 2026 and 2027 seasons after Manly made finals in 2024.
"(It was) an apology to a degree, letting him know that I'm sorry," Trbojevic said of his phone call.
"As a playing group, we're sorry that we couldn't put in performances that we wanted to for him, for the club, for everyone, and this is the outcome.
"We definitely feel responsible and accountable for where we sit and the outcome happening with Seibs."
Club legend Kieran Foran presided over his first training session as interim coach on Sunday, having been promoted from his role as an assistant to Seibold.
The 35-year-old only began his coaching career in November after playing his final professional game with the New Zealand national team earlier that month.
Manly's most recent premiership-winning five-eighth, Foran has already impressed his charges.
"He's an ultimate competitor. If you can't get behind him, then I don't know who you can," said centre Reuben Garrick.
The Sea Eagles will aim to turn over a new leaf from Thursday night's round-five clash against the Dolphins, their first away trip of the season.
"It's got to be a line-in-the-sand moment," Garrick said of the tumultuous opening month.
"We lost three in a row at home. If there's ever a kick up the arse, that's as big as it can get here at Manly."
