and how do you know they need to replace them? you dont.
i "know" things the same way you do: "by reading shit and making up opinions" lol.
in other words, youre right, i have no idea. my only knowledge comes from reading certain stuff and then formulating my usual half assed opinion.
but as to twittwr, it has been written about for a long time in many different places that as an organization twitter has an insufficient business model that has held back its earning potential. a reorg is coming. as to musk's intentions vis a vis twitter's labor force, all new management guts old management after a takeover, and the quickest way to get an increase in profit is to cut the labor costs.
all signs point to mass firings/quittings.
the mainstream press will gleefully report that musk is tearing down twitter as some form of revenge and that he's an evil racist white man out to endanger minorities on twitter. the right will portray him as some sort of avenging crusader for free speech rights against wokist dictators.
in truth, its what happens whenever new management moves in.
