It had a premine. It didn’t ‘run’ in any sort of closed fashion; right from mainnet launch anyone could run a node without a trusted party being required.

So the question that is relevant is: was Ethereum at that time, or even later on, exposed to a low barrier 51% attack? And should you, with hindsight, have taken that risk or should you have used ‘trainingwheels’? Thats what this all boils down to...

Ethereum and other cryptocurrencies like Bitcoin are intrinsically more secure against 51% attacks than Iota, because of their miner incentive and adaptive PoW difficulty. The risk of 51% attacks is simply something you account for if you want a decentralised cryptocurrency.
