Exactly. People are not going to stop watching NBC because of this. It's really not a big deal to most people. Most people want to be able to come home from work and watch the biggest events of the day.
I agree as far as the delay goes, but I think they're handling the spoilers badly. A lot of people are annoyed that they went to http://www.nbcolympics.com/ to find a broadcast schedule, or watched the NBC News before the Olympic broadcast, and were told the results of stuff that hadn't aired yet.
An option could be to double down on the tape delay, and uniformly embargo results until the airing: pretend that when something airs on NBC is when it really happens, at least for NBC-property purposes.
But who am I kidding? Nobody's going to stop watching NBC permanently because they won't air the olympics in a timely manner.
