So, again I see there's quibbles about semantics.
The difference between aUEC and UEC is that aUEC are the currency during Alpha. You can't buy those as far as I can see (dsmart correct me if I'm wrong about this). UEC however will be the currency in the actual game. You can buy those. And in fact, if you go to the CIG web store, you'll see that these currency purchases don't come with any other ingame effect or item. You buy a certain amount of UEC with a certain amount of USD, and that's it. Whether or not the alpha behaves differently doesn't matter, the alpha isn't the real game.
Nevermind the fact that there's a reason that most games today with a cash conversion shop use two different currencies: one you can earn in game, and one you can only purchase with money - since mixing the two brings with it all kinds of dangers and problems (gold farmers, grey markets, market manipulators, etc). That is a separate issue by and in itself.
The fact remains that no matter whether you can also earn UEC in game or not, this is a line that SC has definitely crossed. I should note that until the recent big patch, Planetside 2 has managed to refrain from doing that, but has since added purchasable, consumable construction items that you can also get by spending real money. You may well be ok with this, but the issue here is that someone with deep pockets will always be able to outdo you, because you don't want or can't spend that amount of money. SC is an even worse offender here, because not only can you sink real money into fantasy UEC money, but you can also directly purchase weapons and upgrades via the Voyager Direct shop. Purchases, I might add, which
can be destroyed in-game.
This is exactly why I was glad to see that Frontier binned their plans to offer a cash shop for credits - something that they were at least considering during Kickstarter.
So to reiterate, the issue is not whether or not something in alpha respawns in return for money or not, and dsmart's tweet may well have confused something there (dunno, see my aUEC question above) - the issue is that unless you have sufficient UEC in your account, you may not be able to respawn your desired ship - but they'll be happy to ask you for a small cash payment to make that ship pop up at a landing pad. Every single time.
