He said he can't ANSWER the emails through RCU. So obviously he wants to respond directly to the person. Plus the address may not be the same one used for RCU.
There is a big difference between what you quoted and what was written: "I cannot answer emails that
come thru RCU "
The statement if it is not a dig on RCU is mute because if you click on the address in the post, you can send an e-mail to him and AFAIC it originated from RCU. Do you get my point?
The post would have conveyed the intended message without the last sentence.
