I wonder if Twitter just hung onto market share in India while it hemorrhaged users in the anglosphere? IIRC we've seen this with Facebook in a few places. Basically everyone I want to follow moved to Bluesky or at least is posting their content there too - there's a few local governments that are stuck in 2010 technologically due to indifference or lack of budget that still only post stuff to Twitter but that's fairly unusual, but is infuriating enough for people to post about it.
