To continue playing the devil's advocate:

1. Experts can comment, but I think the value of multi person conversational data from forums is uniquely valuable and in short supply relative to just blogposts/news stories on the internet.

2. The absolute economic value of the entire corpus of Twitter is much more valuable than any single boatforum.com like website. So Twitter has a much more incentive to lock itself down than boatforum.com.
