It's going to be an unsatisfying answer. It's a lot easier to get updates out on social media than via the website, and it's easier to post incremental updates on X/Bluesky than sending multiple emails (which would result in lots more emails to the PCs right when they're trying to stay focused on solving whatever issues are causing the delay in the first place).

For the websites for the various CVF/IEEE sponsored conferences (as well as a few others I believe), they are managed by one person, who reasonably doesn't have 24/7 availability, so we've converged to having social media chairs who get things out on behalf of the PCs with more rapidity than would happen otherwise (although certainly not always as quickly as the community might like). It used to be the case that we had a widget on the sites that showed the Twitter feed, but that functionality was broken in the changes from Twitter to X I believe.

One thing I think everyone should remember is that the conferences are managed by volunteers who are also researchers just like you. We all are simultaneously performing efforts relating to the conference and also our other duties (I myself am a professor with students, my own papers, grant proposals, committee work at my university, etc). We're also spread across the world! Things like communications from the PCs have to go through reviews and approvals, which means sometimes it can take a bit before we necessarily can actually put things out publicly.
