(like do I seriously need No Man’s Sky installed all the time for the once every three months that I play it?)
That sound's like the data is in semi-regular use at least. For me it's more like "Do I seriously need the sequel installed for that other game I haven't even started yet, but am definitely going to start any day now, after years of having it installed?".
The original post includes two gaming examples, so it's actually about both, which is a bit unfortunate, because as you've said, they're two very different things.
I think the examples given are just poorly chosen. When it comes to regular applications and DRM, then yes, that's ridiculous.
On the other hand, when it comes to gaming, then yes, give me all the raytracing and visible pores on NPCs. Most modern games also scale down well enough that it's not a problem to have those features.
Not sure how standard this is, but on Pixel phones the default is no auto rotation, but when the phone detects rotation it will display a tiny rotate button in the corner of the screen for just a few seconds. Best of both worlds IMO.
