You're not going to know that impact, because most of the technical problems that Twitter as a company can have aren't even visible to us.
Sure, images and hyperlinks breaking and not paying the Slack bill and Musk having another mental break makes the front page of hacker news, but will a spam and abuse detection pipeline being silently busted for 3 months do that? A reporting backend that was providing advertisers with incorrect data on their ad spend? Some customer-relations workflow that ruined the week of a group of TAMs, and had revenue impact?
Twitter is a big ship. There are more places things can break than anyone, inside or outside it can imagine. But as an outside observer, the only signal that we can act on is 'Has the ship sunk? Or is it floating?'
Observing that binary state answers a question, but not the question of 'Is the ship working well?'
