Hence we punish those who don't want to take risks. They already get lower yields in proportion to their risk. Why punish them further by fiddling with yield curves, forcing the spread to be artificially larger? When one pulls low yields one shouldn't complain about the government, one should find higher yields. If you want government to purposefully manipulate yields, than of course that would become a political complaint.
