While I’m generally skeptical of boycotts, BDS scares the shit out of Israel. Because I do believe if BDS becomes a global movement it really could change things. I’ll start with the list from bdsmovement.net and then add to the list as people list other companies to boycott in the comments:
Hewlett-Packard (computer hardware)
Siemens (tech conglomerate)
AXA (banking & insurance)
Puma (clothing)
Israeli fruits and vegetables (usually labeled)
SodaStream (idk that garbage home soda)
Ahava (cosmetics)
Sabra (hummus)
Woolworth's. Overpriced as fuck grocery store chain in South Africa that's been pretty open about supporting Pissnotreal. Also everything costs like four times as much. There's literally zero reason to step in one, except to steal/loot or burn it down.
Also the former Isn'treali ambassador to South Africa, Arthur Lenk was endorsing Woolies on Facebook around 2014-15, legit "buy these overpriced as fuck cherries in a small-arse cup for R60 ZAR because they're made in genocidal-apartheid-ethnostate".
