From what it looks like, Twitters revenue was advertisements and a huge chunk of Twitter's workforce was appeasing advertisers (ensuring that Disney / Mars wouldn't be shown next to porn) as well as sales reps who sold such packages to advertisers.

These sales people are now gone (or in the process of leaving) and suddenly Twitter finds it's $5 Billion/year ad revenue in danger.

It's not engineers who need to go out there and convince Disney / Mars / GM / Honda or Kellogg to run $million ads on Twitter. It's just sales.
