I'm not talking about any specifics of either administration, only about having them back-to-back with polar-opposite reactions from most people. I hope that would make anyone on any side think twice before handing "their guy" some fun new weapon, but I probably hope for too much.
Can you elaborate on this please?
It's not that complex. Our personal privacies have deteriorated with either party in power for decades. Both Dems and GOP have voted to extend the Patriot Act and similar acts. Most of the NSA/PRISM drama happened under Obama (PRISM in 2007 with Bush, to be fair) and I'm not sure anything changed by 2016.
So singling out Trump isn't really relevant or even useful.

Unless you have a really short memory, I think you mean POTUS 39→45.
And while by a lot of measures POTUS 45 has been a disaster, POTUS 44 did far more damage to privacy than 45 has (yet).
