I think this is a different situation to Tiktok. What Reels did was slow the growth of tiktok, by creating the same product that 18 year olds loved, but for the more mature 25-30+ demographic of instagram.
But twitter isn't growing. There isn't an audience for a new twitter for people who haven't used twitter before, because everyone who is a potential user for twitter has already tried it.
So I don't see where the growth will come from, unless meta can force lots of instagram users to actually START using text only. But then they aren't actually destroying twitter, just creating a parallel product for a different audience.
