What a great design for a card. TLDR is this : either the runner pay 4 to trash this (or a virus with Imp), or the corp save some money.
The corp NEVER lose money with this card. You'll rez this card only if you rez an ice, which means that on rez, the corp is already at a break even point. Over the game, Cybersand Harvester will allow you to stack ice without paying for it. Not a big thing, but a credit saved is a credit earned. In an emergency, the corp can still trash this asset to get any credits on it.
Ideal for glacier. Leaving this unprotected for a glacier deck is not a problem. Since either the runner runs a server with multiple ices on it, making Cybersand Harvester get more than 2, or the runner check this card and trash it, thus costing the runner some ressources (unless the runner is using 2x Paricia or Scrubber, which are "infinite").
The main issue with this card is that it will compete with other card that give the corp more tempo. As such, it might be better to combine it with some sort of trash punishment, like Oppo Research. Then, the runner is incentized to NOT trash it, and if the runner does so, the combine cost of ressource + punishment will give the corp some momentum.
The art, quote and name of the card combine well together, but I fail to make the link with the ability of the card. Otherwise, everything in this card evoke the reckless ressource extraction of Weyland. Nice.
