Of course science is no longer a search for knowledge since it has been defined to exclude anything that science can not explain or understand.
I think that's an excellent description. When you couple the above with the politics of science, that is, the politics that have been and continues to direct science, then science appears to have lost its objectivity.
Thank you and I agree with your conclusion. Not all scientists do "political" science but some do and they tend to be very visible.
