Given that Tyre is in the South of Lebanon, it is likely that his friends were making anti-Israel posts. It would be very interesting to see what the posts were, if they were really subversive or just promoting BDS - Boycott, Divest, Sanction.

Given that Ajjawi identified as Palestinian, this is more likely, and it would be a legitimate grievance considering that Israel has illegally expropriated much of Palestine.
