Twitter makes its money with advertising so far. In practice, this means that advertisers can place their tweets as ads in the timelines of users who never subscribe to them. Twitter has been thinking about additional revenue from a subscription model for quite some time.
With the new editing function, Twitter is not fulfilling the wish of many users for the possibility to change the posts afterwards. Rather, you can delay the publication of tweets by up to 30 seconds - and still adjust them during this time. For subscription customers, there are also aesthetic innovations such as the possibility to customize the icon of the Twitter app and the color design in the application. (SDA)
