I think we disagree on the connotation of the word "lead."

To me, if someone describes me as a "lead," it implies that they are focused on making the sale rather than on anything else about the business relationship. I would also find it unsettling if a doctor told me that I was a "good lead" because I had a disease they treat.

Jargon is field-specific. In medicine you’d be a good referral (“I’m glad they sent you to me”) or an interesting case. The field does not use “lead” for that in the way that contemporary sales does. Discordant terminology is reasonable to be wary of.

Consider for the moment the two cases of an agent for a player or actor and a doctor. It’s normal for an agent to discuss commission and for a doctor to not, though both will make money off you participating. If you had an agent who said he’s just trying to get you the best deal and “don’t worry about money” that would also trigger red flags as much as a doctor discussing commission rates for referrals.

That doesn’t mean commissions are worse than undiscussed rates. Just that norm-violators are risky deal participants.

Given this discussion, I suspect the best interpretation of your post is not that it is grievance text. It is that unfamiliarity with the terminology of a field has resulted in transferring connotations from unrelated contexts.

To lighten the tone, I am reminded of a HN comment where someone said that “Khan Academy” was a terrible name because it naturally brings to mind a “con man”. Of course, this must have been natural because the two words are homophones in his accent (they are not so in mine). An example of connotation mistaken.
