Your point is basically the same but I believe he isn’t technically a one man dev anymore. For a while, he has worked in a small team, with a few games released/in EA on Steam having been created by former SV devs on the same engine with ConcernedApe’s permission.
I assume he also outsources the work of the console ports.
In any case, it doesn’t take away from the point, and you could probably still classify him as a solo developer for the purpose of talking about his upcoming Willy Wonka simulator. It’s much easier to pay 4-5 people from the proceeds of one of the best selling indie games of all time than it is to pay 40-50 people from the proceeds of a 10 year old game with free updates and expansions. No Man’s Sky, for example, must have some really consistent sales figures for them to continue to be making money.
Apple made 4 billion in 2023 from selling advertisements on their devices. Sure, it’s only ~1% of Google’s ad business buts still technically billions
