Yes it's selfish and self centered to limit other peoples purchasing opportunities because of your own personal opinion.
Other people putting in pre-orders who aren't happy with those pre-orders can cancel for a full refund if they find the terms unacceptable, no harm no foul.
OCUKs reputation is something that they have to manage themselves. They can do that by managing expectations of the people buying by simply putting a rough (over)estimate ETA on the cards saying 3+ month wait or expected 2021. I've always said this the entire time, even before this thread started, that managing expectations is key for their reputation and they OUGHT to do it, but they're not. But doing that and how they maintain their reputation is quite frankly their business, if they want to tank it through managing expectations badly then that's their prerogative. But it's not an argument for closing pre-orders and screwing over people who want to get in a queue.
I also have a pre-order order queue from day one, but if I was coming into the market right now to buy the GPU as many people still are, I'd want to have the ability to pre-order. So you think that my options should be limited to not being able to pre-order because of your lame opinion on the subject? Yeah thanks, that's not selfish and self centered at all.
