How long do people think this subscription thing will last? "It's cheaper per month than one Starbucks coffee" stops working when you have to pay for 100+ Starbucks coffees per month... and then the subscription bubble will crash.
Maybe the app in TFA is one too, it does need constant updating because the browser is a moving target right now.
However that doesn't go for the other 3 million productivity apps that want a subscription.
You are correct that as the number of subscriptions continues to proliferate we will at some point hit subscription saturation, but luckily, with most subscriptions it's as easy to unsubscribe as get started in the first place.
From an HR perspective, I'm sure organizations are already feeling this pain as they look at all of their different teams and the amount of money they are paying for subscriptions.
