I assume they mean ads for other shows on the same platform(at least Netflix and Prime Video do this), which in my experience not everyone sees as "ads" in that sense(I still do myself).

* Some of these platforms have cheaper tiers that are ad-supported.

* All of these platforms favor algorithmic recommendations (which are ads) over your personal content queue.

* A lot of content on Prime forces you to watch an ad of new Prime content before your show starts.

* Some of these platforms have auto-playing previews that distract you while you are navigating. Sometimes you can disable them, sometimes you can't. Sometimes the setting resets itself. These are ads.

Then you're paying at a higher tier.

Incorrect.

That’s due to ad blocking: it doesn’t make creators not want to make rent, it just means more ads in the content and things like sponsor products being woven into the content. Worse for everyone but people are going to chase money if their income declines.
