Ben Werdmüller sees the Musk take-over as one of more signs that Twitter as we know it is sunsetting. Like FB it is losing its role as the all-in-one communal 'space'. I think the decline is real, but also think it will be long drawn out decline. Early adopters and early main stream may well jump ship, if they haven't already some time ago. The rest, including companies, will hang around much longer, if only for the sunk costs (socially and capital). An alternative (hopefully a multitude as Ben suggests) needs to clearly present itself, but hasn't in a way the mainstream recognises I think. It may well hurt to hold on for many, but if there's no other thing to latch onto people will endure the pain. Boiling frog and all that.
