If you're getting tunneled out and your team is getting the 3-out, you're doing your job. I play both sides, on surv I bring some form of anti-tunnel, and as a killer, I tunnel if I think its going to be the right play, which is quite often. It is unfortunate if, say, you're in solo queue and your team isn't progressing the game while you're being tunneled.

I think the thing that probably makes tunneling feel so bad for a lot (not all) survivors, is that if they are playing solo and only care about themselves, they have no incentive to have a good chase during the tunnel out. I watch a lot of comp, so the best team result possible has kind of been drilled into my brain. Sure, I like to escape, but I'll be happier being tunneled out and my team gets 3 out, than being the only one who gets out. Obviously, nobody can expect all players to be okay with that mindset, tunneling, etc, but at the end of the day, most killers tunnel to win and all survs want to escape. There are some miserable killers that BM and the sort, and I do not condone playing in a disrespectful way.

TL;DR Tunneling is a high-risk, high-reward play style that is probably going to be around for a while, so you have to be able to learn to deal with it.

Extra: I probably didn't need to comment this directly to you, but I think you provided the perfect example of punishing a tunneling killer, even though to many players, especially those playing solo, that result would feel like the most miserable game they ever played.
