Earlier quoted context omitted.
Melinda Gates worked at Microsoft when she met Bill. Should he be publicly tarred and feathered like this? By your logic, he abused his authority and he should not have dated or married his wife because he held power over her - he could have immediately fired her if she had rejected his advances. So where do we draw the line, and why isn't Bill on the firing line in the same way these others are?
That was still a risky move. The key (literally, one of the elements of sexual harassment) is whether the advance is welcome. I'm guessing that Bill used a lower-risk way of finding that out than sending a text message after a job interview.
Companies should prohibit all internal fraternizing and fire anyone who is caught breaking the rules.
VCs and anyone involved in hiring should have even stricter guidelines. If you are an investor, relationships with anyone who owns another company should be off limits. If you are involved in the hiring process in any way, once the company you work for is disclosed, any potential relationships with that party should be off limits.
Tech has been singled out due to the current news cycle narrative. Many other industries are extremely hostile; expect to see plenty more stories in the future. The biases may not all be gender, but could be things such as seniority, ethnicity. Nepotism and general corruption is rampant in other areas. This is not a US problem, this is a global.
