At least 3 members quit in protest over Alibaba's recent membership

Jack Ma, chairman of Alibaba Group Holding Ltd, has canceled a speech at an anti-counterfeiting conference in the United States after the trade group behind it suspended the e-commerce giant's recently gained membership.

Alibaba has been dogged for years by accusations that its online shopping platforms were conduits for counterfeiters and critics say it has not done nearly enough to stop the problem.
