Here is where you can find the complete roll of shame - the list of corporate donors and contributors to the Genocide Olympics in Beijing.
To assist people in boycotting the services and products of those firms seeking to promote themselves at the expense of the liberty of Tibetans, the democracy of the Burmese, the hunger of the North Koreans and the right to life of refugees in Darfur, I've listed below their rivals who you can use intead:
Scumbag Sponsor Firm - Rival Firm you can use instead
Coca-Cola - Pepsi (or better still, avoid tooth-rotting cola)
ATOS Origin - Literally thousands of alternative firms
General Electric - Thousands of rivals depending on sector
Johnson and Johnson - Body Shop (or use natural/artisan products)
Kodak - Nikon for cameras, Lexmark for printers
Lenovo - Dell, Acer, HP all do better PCs anyway
Manulife - Thousands of financial and insurance firms
McDonalds - Burger King (or better still, eat healthy)
Omega - Rolex, Timex, Cartier, Tag Heuer, etc, etc.
Panasonic - Sony, LG, Pioneer, Phillips, etc.
Samsung - Sony, LG, Pioneer, Phillips, etc.
Visa - Mastercard, Amex.
Volkswagen - Ford, Renault, Mercedes, Toyota, etc.
Adidas - Gola, Nike (though they've a poor history too)
UPS - Fed-ex, DHL
Haier - Whirlpool, Siemens, etc.
Budweiser, TsingTao, Yanjing beers - Drink your local beer
BHP Billiton - BP, Shell, various metal processors
Great Wall Wine (It's truly muck) - Something tasty from France, Italy, Oz, etc.
Beifa Pens - Scheaffer, Cross, Parker, etc.
Schenker Logistics - Bax, DHL, Fed-ex, Geologistics, etc.
Technogym - Nautilus, Oemmebi, Weider, Weslo, York, etc.
Don't forget the Scumbag Suppliers too:
Education First - Study somewhere else instead of China
Der Floor - Respol, Hytech, Premfloor etc.
Liby - Daz, Tide, Total, Lenor, etc.
Price Waterhouse Coopers - KPMG, Ernst and Young, Deloitte and Touche
By the way, don't forget to also boycott subsidiaries. For example, Volkswagen also own Audi, Bentley, Skoda, Lamborghini, Bugatti and Seat. So don't just boycott the leading brand, boycott ALL the firm's output.
A simple background check of any of the firms above online, especially via wikipedia, should reveal a list of their subsidiaries.
Do let firms know that you're boycotting them and why. How can corporate scumbags be expected to learn if we don't tell them why we're withholding our custom?
