Most of Googles products are also geared towards encouraging people to develop a habit of not deleting things, which creates a very different situation.
So while this may not be a big problem at the moment, we'll see. I see Photos suggest that at my current rate it'll last ~4 years before I'll need to start paying, which isn't awful, but it's a question of when not if, and image / video sizes still keep creeping up.
That's with my photo-taking being at a far lower rate than it used to be when my son was younger. I'm not a very social person and don't travel much at the moment - a lot of people will hit those limits far faster.
