This is a different situation though, for a few reasons: first, I actually don't agree, once you've promised the raises, people will reasonably make plans in anticipation of them, so I do think you have an obligation (maybe not a legal one, but that isn't what we're talking about) to give them once you've made those promises. I don't recall the women involved in any of this 4b stuff promising a relationship to any man or group of men, it isn't like they "were going to get it" already.

Second, and perhaps more importantly, the stakes for business and personal relationships are different. We don't generally require continuing and revokable consent for giving someone money, the state can for example issue someone a monetary fine, and that's considered an acceptable consequence for many things. If you promise to buy something, and they then come to deliver it and you decide "actually I've changed my mind, keep it, I'm not buying it from you anymore", the other person can in a number of circumstances sue you for breaking your agreement.

However, if the state were to mandate that someone enter into a relationship, or have sex with someone, as a penalty for something, that would be considered a human rights abuse where the monetary fine would not, and if you were to tell someone that you found some type of flower super romantic, and then they came over with those flowers to give, but you then told them you weren't feeling a connection, no reasonable person would take their side if they tried to sue you to force you into a romantic relationship with them.

To put it a simpler way, if you promise someone a raise, the default state once that promise is made is getting the raise, as in professional matters, honoring promises and agreements is fundamental, revoking it later is therefore taking something from them, because you're changing that default state to something worse for them. Personal relations do not have the same dynamic. It is well known and understood that people sometimes change their minds on romantic and sexual relationships, or sometimes just aren't in the mood anymore. Promises don't carry the same weight, when there exists an absolute right to revoke consent at any point and have things not continue. As such, the default state is "not having a relationship/encounter with a particular person", right up until it happens. If the person in question never decides to enter into that relationship, because they have decided that they don't want to even deal with having one at all, they haven't taken anything from whoever else might have been interested in them, because they haven't changed that state. There was never a reason for a guy to expect one of these 4b women would date them in the first place, and no reason to expect that they wouldn't one day leave again if they did.
