How do you even draw the connection between this person not posting on social media since August 23rd and that somehow being a problem with GrapheneOS? What could that possibly have to do with GrapheneOS>
Pixel 11 was released in August and he asked about it on Matrix on August 31st. Therefore, he didn't disappear after August 23rd. We replied on September 1st and can now see his client sent read receipts afterwards.
Your claim was directly challenged, second green account in a row. Also, make less LLM-like insults, these are against HN rules.
