It's expensive for a zoo to house pandas, since the CCP loans them out for upwards of 1 million dollar (the number in one of the Memphis articles was 1.1 million). And that number is per year, so we're talking an expensive continual expense for the zoo. This alone is a huge financial burden on zoos interested in pandas, so many feel zoos are better off spending that money on different species instead or on other projects that better the zoo (i.e. new exhibits). Furthermore, and this is probably the bigger point for most of us "slandah-ers", that money is going to the Chinese Communist Party. There is little oversight into where this money is going once in China, so many of us are uncomfortable with the idea of zoos sending money to an oppressive government to do whatever they want with. Giant pandas in zoos is a way more political topic than any other zoo animal is, so really it boils down to what someone's views on foreign policy and China are. Getting pandas is a way more complex and delicate situation (some like myself would argue unethical also) than just about any other animal species.
