Those other stories are donators and VIP members of the forum. They donated 10 or 50 bitcoin to support the forum and get a title Donator or VIP and badges. How do they feel about their past decisions today?
I think they feel better than the members considering getting decorated with the Donator tag today only to realize that the fee is still 10 for a Donator tag and 50 for a VIP tag. The prices haven't changed since the old days.
Even things like seed phrases didn't exist back then, so you had to back up your wallet file, and if you happened to receive coins, you had to backup again, if a wallet wasn't deterministic.
This was indeed a real hassle. I can't even imagine how many users most have lost coins for not having the most recent version of their wallet.dat files when they faced hardware failures.
Or like
the guy who threw away his old hard drive that kept the only copy of his private keys that could access 7.500 bitcoins.
However, it should be taken into account that at that time the choice of non-custodial wallets was very narrow (was there anything other than Bitcoin Core?), so it should come as no surprise that Satoshi had just such an opinion.
I know that Multibit gave users full control of their keys, but I don't think it was available in 2010. It probably came out the year after. The choices were indeed slim back then.
