It's quite similar to when I used to run a small cafe and people would say "you can make this yourself", "you can make that yourself" instead of buying stuff in - then they would say "if it hasn't sold by the end of the day, you can just eat it yourself - you don't have to throw it away".

Yes - that was fine when it was just egg mayonnaise. But then Tuna mayonnaise, and Chicken mayonnaise and then grated cheese, and ham....

When am I going to have time to eat all these unsold sandwich fillings? Oh and cakes, and scones....

A small amount is fine.
A few subscription services is fine.

But gradually EVERYTHING wants you to pay a "fair" monthly fee. Until you are spending more on these monthly fees, than you are on the electricity bill!
