The argument is just about how the known probability of existing in a simulation goes up the more intelligent life we know to have existed in a simulation. Keyword being "known" as it's the knowing, for a fact, that the odds exist that makes for an interesting thought experiment, especially when the odds of simulation are higher than not.
The actual probability is inherently unknowable for the reasons you've pointed out.
Unity was sold on no revenue share, just paying for your dev seats. That they not only tried to weasle out of this by inventing an "runtime fee" but also applied it to already complete games is a fundermental break in trust. There's no ammout of walking it back that can fix that unless they're going to fire anyone who thought this was a good idea. Which of course they're not going to do meaning things like this remain in the table.
They're offering to reduce/wave the fee if you're using other Unity services. Given this change has the biggest impact on freemium games that rely on free downloads to get a large install bases and which rely on the kind of services that Unity will give you a discount for using, well, it's not hard to connect the dots. Especially when you remember Unity merged with a ad company recently.
Other than that it might be a way to take a bite out of services like Game Pass or Geforce Now. The deals devlopers get for theses are potentially very low revenue per "install" so it's possible this would make them more money than taking a percentage of the revenue.
The obvious suggestion is Destiny 2, it's a coop Bungie shooter with emphasis on movement. The expansion campaigns are fun and challanging on Legendary difficulty. Only thing it's missing is the physics sandbox.
Epic is currently giving away the the Legacy collection for free which has three of the four current expansions. Absolutely worth grabbing and giving a go as I'd recommend to anyone starting the game to just focusing on going through the campaign as you'll probably have a good, if confusing, time. The big downside is the fact you get thrown in half way through the second game in the serise so if you want to understand the story you will need to look things up.
