1.) There was the me too movement and how women over used the term "creepy" in the early 2010s. This gave men the idea that women didn't want to be bothered, so they listened. It also didn't help that you had feminist propaganda like the infamous Gillette commercial of 2019 that shamed men for spontaneously shooting their shot in public. Even to this day, a man can easily get banned from his favorite gym because he made some woman "uncomfortable"

2.) The rise of online dating and social media not only made shooting your shot more efficient in the sense that you can cast a wide net, but also took away the anxiety that comes with doing it in person. Plus, more and more people are meeting their partners online.

3.) Social media allowed guys to see how thirsty women can be towards attractive men. When you have video evidence of guys like Duke Dennis, Marlon, King 6'8 the great being actively approached by women, plus seeing how women treat men they approach as opposed to men that approach them (less flaking, games etc.), less men will bother to approach. Men also share notes and experiences seeing attractive men they know getting it thrown at them.

4.) The threat of public humiliation is much more intense than it has been in any point in history. Back then, even if a woman harshly rejected you, we didn't have HD cameras in pockets and/or meta glasses to record it. Nowadays having your face plastered all over the internet for the world to see after approaching the wrong woman is a very real risk that men have to consider. Just look at all the "gym creep" videos that YouTubers such as Joey Swoll respond to.
