You hit on a major point, that many don't realize or the more misandric minded purposely overlook. The vast majority of young heterosexual men (arguably 80% or so) simply do not have the same opportunities with the opposite sex, as do most young women in the reverse. This is a matter of both biology and society.
Young heterosexual men have to also compete with older men, who may be already established in terms of socioeconomic position, maturity, knowledge about women, and focus. These attributes, of what older men can bring to the table, can be very attractive to younger women and severely reduce their availability.
Young heterosexual women are often massively focused on and only have eyes for the top 20% to 10% who hit the genetic and/or socioeconomic lottery and mostly have it all in terms of looks, style, build, height, innate charisma, popularity, and/or family wealth. Even when such woman are in the lower rankings (though may refuse to acknowledge reality) and have little chance to realistically get or hold on to such men. Which by the way, can lead to them taking their anger and frustrations out on men not in those positions that don't engage in nor have the opportunities to act in such ways.
Many women, in general, are not even looking or care little about younger men who are not providing any obvious benefits or are as popular. The further the young men are from the top, the harder their struggles with the opposite sex can be. And dramatically way more so, than their female equivalents.
This can be why such young heterosexual men (outside the top 20%) can be resorting to seemingly extreme measures that are incomprehensible to females and non heterosexuals. More so, many women have little to zero sympathy or empathy for the harsh struggles of such young men, and even to the point that such women have misplaced or unreasonable disdain and contempt of males that need to or have to make such an effort. Which can be combined with the ignorance to the realities of the opposite sex, and the arrogance of their position, as women with an easier path in such particular matters.
Many women take attention, sexual choice, and sexual opportunity for granted. It's something they can choose to indulge in (particularly as young women), almost whenever they feel like or the mood hits them. These are options that most young men do not have whatsoever. Which is why some kind of app, doing auditing, or tutoring are even seen as helpful possibilities.
