Not an answer to your question - but as an aside, why the tone? In the classic HN example, isn't Dropbox just an inferior Rsync?
Eg, if someone wants to clone something and it manages to succeed, they clearly got _something_ right. Either a captive audience, a better UX, a better pricing structure, etc. There's almost always room for ~innovation~ competition, so why poke fun at it?
I suppose if you think it's truly inferior in every way compared to Caprover your tone might make sense - but even then, i've never heard of Caprover, if i was a customer looking for this product (and i may be) i'd probably have defaulted to DigitalOcean for this. If that alone ends up being profitable for them - a Caprover clone with a well known name - why wouldn't they do it?
I see these types of "HN Dropbox" comments on HN so frequently and i just don't get it. There's lots of angles to product viability, and these comments seem to be purposefully ignorant. Not saying you are ignorant, just that the comments seem to try to ignore any logical reason for competition.
