In July 2019, Yoshinoya, a Japanese fast food chain, created a Facebook advertisement mocking local police for removing notes from a Lennon Wall.
The advertisement was taken down shortly thereafter, and the company's Hong Kong branch announced that it had fired the employees who created the post.
The decision prompted supporters of the protesters to boycott Yoshinoya.

In the same month, a captain from Cathay Pacific made an announcement reassuring his passengers that the airport protests were peaceful and orderly.
He ended with a few words in Cantonese, saying: "Keep it up, Hongkongers!
Be careful and stay safe." (
香港人加油，萬事小心) Soon after, the captain was reported to have left the airline, but it was unclear whether he resigned or was fired.
Cathay Pacific has since been criticized for alleged political bias.

Following these incidents, citizens supporting the protests developed their own economic circle by boycotting blue shops and solely patronising yellow shops.
Several smartphone apps, such as "和你eat" and "WhatsGap," were developed to help citizens identify and avoid spending money at shops with opposing political views.
