whenever I see people write (or say) "on X, formerly known as Twitter", I want to yell that we, the users, control this technology.
Leaving Twitter has been popular with many, but an add-on like Control Panel for Twitter let users change what is displayed, logos, almost everything about the visual appearance .... BECAUSE THIS IS THE WEB.
One of the huge positives of web tech is just how much users can be in control, if they choose to be.
And we can, if we want, also choose what to call it.
