Twitter must be bleeding DAUs.
There are other indicators too.
After the takeover they dropped the login wall, but it is back, and way more aggressive than before. You can't even scroll down to see more tweets now, or view replies.
The ads are also really weird and odd. Either their ad targeting system is broken, or they just lost so many advertisers that they have nothing good to show.
I bet the initial influx of previously turned away users is over, as well as the returning users just there for the show, and now the effects are compounding.
