If the comments load in after the page loads, crawlers are unlikely to see them, so you're not getting much SEO benefit.
Worst case is off-topic comments that take time to remove, significantly worse than nobody using it.

They actually have a deal with google where all of their comments are directly indexed and attributed to the sites (likely similar to canonical references).
It used to be a problem a couple years ago, and sites would then use the API to load in comments and include them server-side. Obviously this wasn't ideal, but it's a solved problem now.
Plus I don't think it's such a bad idea from a reader's perspective. Seems like the worse case scenario is that no one uses it, and the best case scenario people are able to contribute to improvements.
