I've seen GM Hess, GM Naroditsky, IM Bartholomew, IM Rozman playing total crap to flag their opponents.
Flaggers

What happens a lot of the time is I create a position on the board that is absolutely winning, but it can be hard for me to find mates, so I lose on time. And what’s frustrating to me is when the time is neck and neck, and the position is lost for my opponent. They beat me by a few seconds in a position where they absolutely could not win. Like the video you posted. Tell me Magnus is going to win that game…
I’m glad you shared that video about Magnus. Why would he argue that it’s a win for him? That seems unsportsmanlike to me. Is it possible for him to checkmate his opponent with only a bishop in that position? Of course not. His opponent has three passed pawns, the promotion square for each pawn is a light square and black only has a dark square Bishop. In order to checkmate with only a bishop it requires very specific circumstances. Shouldn’t even be an argument, that’s just my opinion. He was outplayed in that game. I’m not arguing it should be a win for white, it just shouldn’t even be a conversation whether that is a draw or not.
At 4:27 it shows a sequence of moves that leads to black delivering a checkmate to white. That's why judges assigned a win to Magnus.

Dude stop making a fool of yourself . At least know the rules before you speak

You need to read the right books:
Incidentally, in a 3 2 blitz game a few minutes ago I missed a simple mate in two with two queens.
White to move:

Instructive. Thanks.

Of course I know the rules. How many times have I said that this is about etiquette? How many times have I said I’m not complaining about the rules, I am complaining about the players? How many times have I said this is just my personal opinion? At this point you are just being a troll.

I get it, technically it’s a possibility so he was handed the win. I just feel his opponents pain because there’s no way that that situation is happening, not a snowballs chance in hell of Firouzja making those moves. And that’s why, for the 10th time, in my opinion I would respect Magnus quite a bit if he said to his opponent and the judges, let’s call this a draw. Again, that’s just me though. Although, not sure if that’s even a possibility. As far as I know, maybe there’s no way around it, it’s just a win for black. The draw would have to be agreed while the game is happening, right?

Yes. But defending the position that Magnus was defending makes it violation of etiquette to be the one to offer the draw. Firouzja is clearly winning, but needs to do the work on the increment. After Firouzja's time expired, Magnus claimed the win, which is appropriate. In blitz, people often lose on time. It can happen at slower time controls, too, and very nearly did in the WCC.

Dude what the heck is wrong with you ? I know its a bit sad for Firouja but its utterly disgusting on your part to call for a draw in that scenario

As for the drama between Magnus and Firouzja , here's a better video where Magnus explains everything .
Start it from 1:07

Ah, that makes sense. Didn’t think about that. That happens on here a lot too, the person clearly losing offering a draw repeatedly.

It’s so disgusting! Ha ha. I’m just gonna stop responding to you. I’m also not seeing a video in your last comment.

The one who is disgusting is you . There's one thing about sportsmanship is that it's subjective . If you feel some actions constitute poor sportsmanship , then you are entitled to your opinion. But calling for decisions to be based on what you think is the right thing to do morally instead of going by the rules is outright rubbish

It’s so disgusting! Ha ha. I’m just gonna stop responding to you. I’m also not seeing a video in your last comment.
Ok so your calling it a draw. Everybody knows that magnus, as of now, is somewhat better than alireza. So in a blitz match, you can either play slower at the start and hope you can find the right moves at the end or you can play it fast but get worse positions. Alireza chose 1, and magnus chose 2. Now your saying because magnus chose 2 he's not allowed to flag, which is essentially saying he's not allowed to win. So your pretty much saying everybody has to go option 1 which is just freaking ridiculous.

I’m not saying anyone “has” to do anything. Don’t put words in my mouth. I’m saying it would be respectable if Magnus shook his hand and said, you got me, good game. You deserve the win, this is lost for me. This thread is getting to a point where I’m literally just repeating myself over and over and over. I respect resignation in lost positions, people disagree with that which is fine. The end.
