No one asked if it was silly or hypocritical.
The question I answered was:
... is it ethical for scientists to deny the fruits of their labor to people that reject scientific fact.
There was a second question in the OP though as well. It was:
Is it also ethical for creationists to use a technology that was made from an area they are against.
That is closer to what you are saying but it is still couched in the terms of ethics.
I would have to answer the second question as a resounding YES!
