Why did Clubhouse fail?

Launched iPhone-only, millions of Android users locked out on day 1. Everything was live: arrive late, you missed it; room ended, content gone, no replay, no library. It recorded your conversations while you could not record them, a privacy and GDPR minefield. Endless rooms, little signal. Then the pandemic ended, FOMO died, and Big Tech copied social audio overnight. 10 million weekly users and a $4 billion valuation in 2021, half the staff gone by April 2023.
