Okay, I have read up on the issue and now understand that Elon Musk wants to create a plattform equal to the chinese Wechat.
Background:
Elon Musk's plans for Twitter seem to carry links back to the entrepreneur's very first corporate success. In 1999, he co-founded X.com, a financial services provider. The company later changed its name to Paypal and was sold to Ebay for a multi-billion dollar sum. In 2017, Musk bought back the domain name "x.com" from Paypal for an undisclosed sum. Shortly afterwards, he himself wrote on Twitter that at the time he had no plans for the domain, but that it had great sentimental value. Anyone who visits the domain name today is greeted by just one letter - an "x" against a white background. The acquisition of Twitter is an accelerator for the creation of X, the everything app," Musk wrote on Twitter as recently as early October, adding that it was about the "original vision for X.com." Exactly what Musk means by an "everything app" is not clear from his often rather cryptic Twitter posts.
However, the role model seems to be the Chinese app Wechat, which like "X" can also be described as "an app for everything". In addition to communication, the app also offers its users everything from booking doctor's appointments, ordering food to payment services.
I hope he fails. It is not at all good that the concentration of power or control over our media is concentrated to a few white men in the United States. At the same time, it is easy to launch new apps and the chance that someone will create apps that are better than the ones Twitter can create is great. Here comes the problem with that big companies often kill smaler ones by buying them up at a premium. We'll see how it goes.
