The other half value of Disqus is to provide comments to static sites. Back in the days, most sites used dynamic content, and had comments as part of the CMS system they used. Today, lots of sites have no back-end database, and unfortunately, lots of such sites use Disqus simply for convenience. Convenience that hurt the sites, and their visitors (slow load time, unacceptable tracking & spying). Any alternative should be welcomed.
If the sites that use Disqus today were willing to pay for an alternative, I would personally offer hosting of such, with fast load times and no tracking. However, I don't believe such willingness exists, and people are getting conditioned to accept sluggish load times and tracking. Too bad. Self hosted Open Source solutions are the second best alternative - management gets the illusion that the thing is free, and you actually get fast load times and no tracking.
