Source of this is from Matthew Prince, Co-founder & CEO of Cloudflare posted at 11:34 Jul 9,2023. It was posted to his twitter (@eastdakota). Not linking to twitter bc don’t want a deadlink next time twitter makes API changes. And not to drive traffic to twitter :D
Edit: July 11th update, arstechnica published a detailed explanation
Well this probably doesn’t measure any app user
App users still make API calls to Twitter’s domain. Depending on the domain name, these app users might still be counted.
not a definite measurement for a decline in users but I would argue it shows a trend of less users visiting the site
