interesting - I just got a notification from Dropbox

"On Dec 14, 2018, we're saying goodbye to the events RSS feed. We think some of your team members may have used this feed.

We're focused on building better tools for viewing and monitoring activity, for admins and users alike. Here are some other ways you can see what's happening in Dropbox"

I don't see any relation, but could any factor have influenced the timing of these announcements? Or is it just a coincidence that two large co's drop RSS within hours of each other.
