No, if you want to establish correlation or causation, you have to prove it. Don't have access to the data to prove something? Sucks, but then you can't draw that conclusion, at least not definitively.

I can believe, though, that you're at least somewhat correct that the mass firings were responsible for Twitter's decline. But it's plausible that other things are also to blame, and possibly even primarily to blame: questionable product decisions made post-acquisition (Twitter Blue, lax moderation, requiring logins to view, ...), the volatility and offensiveness of the new owner causing advertisers to leave, etc.
