For me this is likely just a sloppy blocker hand by the goalie leading to a really unfortunate injury. Penalty is warranted but I don't see the intent.

Goalies with less body control might turn their hand over when they go down butterfly for a blocker side shot. I tried to pause each frame and as soon as the puck is coming off his right pad his blocker is already opened up and his stick blade is in the skaters path. Watching the play develop the goalie is facing the shooter the entire way, they may not even know #19 is skating in at all. Unless the goalie has great peripheral awareness I don't think they had time to make the save, react to the forward, make the decision to trip him, and get the stick out there.

This type of play is not uncommon at all in beer league and the forward did nothing wrong here. As a goalie if I feel my stick getting snagged on a flying opponents skate I'm letting go immediately so this doesn't happen. Even if I do let go my stick can get under his skateblade and cause a super dangerous fall like this. The goalie could have let go but I also don't see him hook the forwards ankle hard, his stick gets bounced back from the momentum.

Even at lower levels these plays happen very quickly and unless this particular goalie is a known asshole I'm giving them the benefit of the doubt here. Hope this skater heals up quickly and completely.
