Doesn't strike me as particularly immoral.
yeah just like laying claim to the most fertile land in your region, doing nothing with it, and waiting until your neighbors are sufficiently desperate to sell it to them for gigantic markup
hugely value-added activity, and a well-earned increment.
Zero added value while getting a money inflow ticks my box for immoral.
The one takeaway I got from my engineering ethics class in college was that everyone has different morals. Debating if something is “moral” or not is useless. Education on a subject is useful, but once someone understands your point of view and still thinks it’s within/outside their morals, there’s nothing more to discuss.
I don’t know about immoral, but it is at the very least a bit sleazy. When I look for domains for side projects, I very rarely have to abandon a name because it’s been taken by an actual operational service; it’s almost always because someone is squatting it with a “parking” page filled with sketchy ads that they’re paying almost nothing for. That isn’t doing any good for anyone besides the squatter.
