Yes, government agencies funded by the taxpayer, with scientists directly employed to work for them. In much the same way, I wouldn't expect a person working for the DEA to be allowed to publicly say "legalize it", and I wouldn't be particularly outraged if in fact that is banned.

I use this term to contrast to, e.g., university researchers receiving an NSF (or Canadian equivalent) grant and (in name, at least) given political independence.
