I felt this way for a while, but I’d like to offer another angle: maybe it’s like saying “Every company eventually hires tall people. Some have no tall people, but it’s just a matter of time. Tall people are really an unstoppable force.” The missing piece is also observing short people (ad-free offerings), which you’d notice are not being eliminated, are also prevalent, and also “infect” everything. I think the unstoppable force being felt here is just statistics: ads are often an option, companies make a lot of decisions, it’s statistically inevitable that some of those will be ads, unless the company has some strong aversion to ads, which most don’t.
