These pardons come under exceptional circumstances, as their recipients are public servants who have been threatened with blatant political prosecution. Biden justifiably took protective measures against Trump's potential abuse of power that could devastate the lives, safety, and financial security of public servants who faithfully discharged their duties — even when they've done nothing wrong and would ultimately be exonerated.
These preemptive pardons by an outgoing president imply the opposite of what Biden said. Corrupt public officials like Cheney and Fauci know they're likely guilty of severe wrongdoing, which is why their friend Joe Biden stepped in to cover their tracks to avoid investigations into the mishandling of Jan. 6 and the COVID pandemic, among other dubious policies and decisions.
No matter who the president is, preemptive pardons go beyond their intended use of such powers and set a dangerous precedent. Not only are pardons not meant for people who have yet to be charged, but using them in such a way makes the supposedly non-guilty people in question seem very much guilty. This brings a series of complex implications.
