Update: May 18, 2023. It took a few weeks, but Twitter finally shut off our API access. Though we were in limbo for a bit, we can now confirm that our services have been disconnected and Twitter is no longer part of Jetpack Social.

Finalmente el día ha llegado. Ya no hay auto compartición de post en Twitter mediante JetPack. Yo seguiré haciendo pruebas con mi instancia de WordPress con Activity Pub y friends a ver que logro. El resultado me esta gustando, aunque sigo con pocos seguidores jajaja.
