It seems a significant amount of that revenue is now from services (App Store, in-app purchases, subscriptions,…).

Yes! And these are very easy to boycott! I don’t understand why this didn’t happen after Tim Cook shove that gold bar right up Trump’s ass.

This leads me to believe that most boycotts gain traction only if another corporation stands to benefit from that. Nowadays pretty much all of the big players are in bed with the current administration, so there's little surprise that boycotts aren't noticeable.

A beer company had 10% of their value go away because they dared to acknowledge the legitimacy and humanity of one trans person.

Boycotts work great. People just don't do them for anything it seems.
