The context is missing which is very important for any judgment:
For example, if they asked you to share your capx because you needed help with some issue in your code then:
Definitely Not
Never share your capx even if they get angry, the truth they shouldn't get angry and instead they should encourage you to get used to not sharing your Capx for obvious reasons.
It happened to me many times in the past that some users shared with me their capx because they needed help and I had to tell them off very serious that you should never share your main project capx and instead do a quick demo example reproducing your issue. You have to remind them of the consequences of doing that which could be catastrophic.
