In the "old days" there was a different societal view of a whole lot of things at play here (generalities abound here, and of course do not apply to all people at all times; these are also not statements on right or wrong, just observations on the way things are):
Women have more sexual agency now, increasingly viewed as persons with active desires rather than as objects to be conquered. The fact that she wanted someone sexually is not inherently shameful anymore.
Affairs are still shameful, to be sure, but not to the extent that they used to be, and especially not within places like the FBI, where you spend significantly more time with your coworkers than with your spouse, and often in remote locations. I have friends and acquaintances who have gone through the clearance process, and it's not about what you've done - it's about what you are unwilling to admit to. This attitude is good, as it makes sure people with sensitive information cannot be blackmailed, but it also gives a more cavalier perspective concerning one's actions in one's personal life.
In the current digital age, there is an active struggle between what is public and what is private. Should celebrities expect their text messages to be private? Should teenagers? Public servants? Where should the line be drawn? When the line is crossed, what is the punishment and whose responsibility is it to lay out the consequences? It is a grey area, more so than ever before. A lawsuit like this may not be about the Trump Administration or Congress at all - it may be a bid to challenge privacy issues on work-issued technology, which would have far-reaching implications.
We can certainly discuss whether these changes are good or bad, but they have happened. Denying them, acting as though things haven't changed, is what makes someone out of touch.
