Kevin Systrom, Instagram co-founder, testified at Meta's monopoly trial, accusing Mark Zuckerberg of deliberately hindering Instagram's growth out of jealousy. Systrom claims Zuckerberg diverted resources after the Facebook-Instagram merger, fearing Instagram's superior ad revenue. Internal emails from 2018 reveal Zuckerberg considered selling Instagram to curb its growth, coinciding with Instagram surpassing Facebook in ad revenue per user. Systrom's departure in 2018 followed this perceived sabotage. This testimony contrasts with Zuckerberg's earlier statements about Facebook's mission to expand social connections.
