It's fine to disagree or be critical in a substantive way, as many others in the thread have done. But it's not fine to arbitrarily reduce a subject to something ugly and trivial in order to demean it. In addition to being uncivil, that's off topic, since when you do that you're not engaging with the actual thing.

(Edit: I originally said "What's not fine is to spew reductionist bile"—but this also breaks the site guideline against name calling. Sorry! Not always the easiest rule to avoid breaking.)
The comment makes two reductionist moves: it casually substitutes one thing for another as if the two were the same, in order to tar one with derision proper to the other; and it uses the modifier "merely" followed by something trivial in order to demean the subject. I don't know what you call reductionism, but to me that word is not only justified, the comment is a poster child of it.
If I wrote yet another minimal lisp implementation in a weekend, and marketed it as if it was going to best Chez Scheme in all benchmarks, and someone came along and told "yeah but this is just a reiteration of sth. we already had, nothing new here, and your ways seem a bit shady", would we have to discount it as reductionism?
You might disagree what people think, but you should not think and decide instead of them. I appreciate the work you do as a moderator of this fabulous community, but in this case you're openly siding with one side of the discourse. Either do not do that, or add to the guidelines that "HN moderation will vouch for what HN companies are doing, disagreements on their busines models are unwelcome". And also, while at it, I can not vouch for the comment I'm talking about, and I would rather.
Step 1. Allow Promise to amass a useful amount of people who are awaiting trial/convicted of minor crimes.
Step 2. Suddenly threaten to shut them down and immediately incarcerate all the people that Promise is keeping out of jail, unless they give your corporate donors access to their captive and monitored labor pool.
Step 3. If this goes well and makes everybody money, assist your donors in a corporate takeover of Promise.
