Abandoning instead of resigning

I resigned a game after 14 moves a few weeks ago when I got unexpected company at my house while I was playing. At the time my opponent and I were in about as even a position as you could get. We both had played with 90 percent accuracy to that point and had a 1,550 game rating. The material was even, but I actually felt I held a slight advantage as I had the bishop pair. But I play 60-minute games and still had 43 minutes left on the clock, so I just resigned the game rather than make my opponent wait out the time. I thought it was the courteous thing to do. Hated to take the loss as it didn't help my low rating, but sometimes that's the way it goes.

First suspects to be investigated here should be the rating system, and the fair play enforcement. 
I've said this before.... People are fed up with being gaslit by a sandbagged matching algorithm and/or engine moves popping the exact same "openings" and mopping them with embarrassing ease, dragging the games out letting opponents feel they have a chance to gain advantage; just for every intensely calculated plan to crumble before it can even begin. You can blame the players all you want. "Git gud" isn't even a factor when talking about a system that *claims* to match players with other players of most similar skill level-- but it's really half engine users playing at twice their rating, or actual complete noobs that need to be treated with kid gloves, lest they think YOU'RE using engine moves.
Smh. This site is a complete clownshow and I eagerly await the inevitable scandals to be revealed behind the scenes here. Watching supposedly 2300 matches blunder harder than some 300's, watching 300's play better position and accuracy than 2300's? 
....lmao there's definitely "levels" to this, and they want people to MOSTLY stay in the place they're put by the algo, period. 
This isn't wild eyed conspiracy or nihilism, and everyone with any level of human intuition knows something stinks around here.

I really like the feature that the game ends as abandoned after 15sec when in a losing position, so I hardly lose any time.

Is there another rule in tournaments? Once my opponent blundered a piece and had me waiting for like 7 minutes (was a 10+0 tournament).

@Igor_Vo, unfortunately your opponent is entitled to use their time in whatever way they want, including seven minutes of pointless wait after a mistake. I don't think this is always malicious. Sometimes, psychologically, after we've done something stupid, we just get stuck looking at the situation in disbelief and hoping that if we look at it long enough it will turn out not to be as bad as it obviously is.

It looks like the comment sections on chess sites are no better than anywhere else. So much for this noble game.

Guy I played today suddenly resigned after 23 moves, which surprised me. I had a better position, but the material was still even, and there was plenty of time left on the clock. Maybe he had something else to do. Too bad, as I would have liked to see how well I would have ended up playing the game out.

I think it would be great if those who showed poor sportsmanship were now forced to play others of their same ilk!

Most people that I play abandon games rather than resign, and it's what I've begun to call "the chess.com etiquette" these days. I wonder if the resign button wasn't hidden under a menu in the mobile client, would that make a difference?

Then there are the few, but still non-negligible number of people who just sit there after blundering, letting the time run out sulking like a kid who is refusing to eat their vegetables. Ultimately it is their time and they can do what they want with it, but I do also think it's kinda embarrassing to just sit there. Always reminds me of the time Hikaru just sat there crying after losing to Magnus. And no, I'm not tormenting them by promoting all my pawns to different pieces and trying to place them back to their opening positions or anything.
