I think this is really merely the latest in a continued assault against Twitter and free mainstream social media. They tried to make their own services that directly competed (eg Parler), they failed, so now they’ve bought Twitter with a leveraged buyout. Either Twitter becomes what they want it to be, and they invest further to cover the $13bn debt, or Twitter dies from the debt (which would not have existed without the buyout). With the current value of Twitter being estimated at less than this debt, the latter seems much more likely now.
