Reading the methodology of the underlying paper makes this estimate seem quite dubious. Quoting from the paper [1]:

> Due to lack of data, we assumed that revenue per minute of platform use was constant by age.

Surely ad rates targeting minors without disposable income are much lower than for age demographics with higher spending power.

I'm happy to have an excuse to discuss our opinions on the ethics of social media use by minors, but I'd appreciate if the "science" was a little more forthright about what we know and don't know.

In this case the paper seems to make a reasonable estimate of the fraction of total social media usage time spent by minors. But it's sloppy bordering on dishonest to extrapolate that to revenue numbers without looking at any data on ad pricing.
