I think the take is: If 100k people watch the episode, spending $200 more for higher quality subtitling comes out to... a whopping 0.2 cents per person (per episode). Let's just say that would cost an extra $1/month per person. Are they price sensitive enough that they won't go to a competitor that's a few dollars more expensive per month if it has better subtitles? I don't know, but maybe some manager believed they were, and thus it was worth it to make the subscription a little cheaper.
