The GP was mostly downvoted because of the unnecessarily supercilious tone. Instead of explaining why they thought Venus was better for this purpose, GP just chose to end with a haughty-sounding "I don't think they have thought this through." Considering GP is a random stranger on the internet, and "they" is SpaceX/Elon, the downvoting is natural.

Maybe. But I think that it's, precisely, because we are random strangers in the Internet and we all know how easy is to misunderstand intentions by text, that we should think two times before downvoting.

It's my personal opinion that downvoting is used too easily in HN.

Sometimes it seems that we are trying to filter opinions that we don't agree with, instead of policing good manners and filter irrelevant to the subject comments.
