One of the things the article is complaining about is that many apps look like they are free in the store with an optional subscription, but once you've downloaded them you find out basic features are locked behind a subscription.
Personally the worst trend I've started seeing is "free" apps that are great for a few days until you find out they've been silently giving you a free trial of the premium subscription and now you'll have to pay up to keep using basic features. They're hoping now that you've spent some time learning and using the app you're invested enough to start paying to keep using it. You could be getting yourself into one of these apps and not even know it til a week later, it's infuriating.
I did some test on my deck when I first got it seeing the difference in load times when a game was installed on its m.2 SSD vs a Micro SD card and the difference was there but pretty negligible. a long load time that took 16 seconds on SSD took 18 on Micro SD. It isn't something I'd personally notice unless I was timing it.
