I've stayed on Twitter for a number of reasons, including functionality, archival purposes. and ease of use. I'm also just stubborn, and don't want Elon Musk dictating how I use social media. I use Twitter for me, not him.
After tonight's purge of journalists, that stance may no longer be tenable. I'm honestly not sure what Twitter is anymore, except the plaything of a thin skinned man baby with too much money and too many enablers.
