If you live in the West, you can potentially support the revolution in Egypt by organizing against companies that are profiting from the coup.
You can contact the executives of these companies, protest in front of corporate headquarters and retail branches, try to take out an ad in the newspaper calling for a boycott of the coup, etc.
You can deface billboards and other signage with slogans that implicate the company in Sisi’s crimes.
Shift the focus from demonstrating, for example, in front of government buildings, and instead, direct blame at the companies whose profits from Egypt are drenched in the blood of Raba’a, and based on the overthrow of democracy.
Establish in the public mind a connection between business and the coup.
Customer-based companies, retail chains, etc, are more sensitive to negative publicity.
Study the international campaign against Bechtel that eventually drove them out of Bolivia.
Make it clear that these companies are absolutely complicit in human rights violations and political repression.
