Perhaps the actual problem then are these monolith platforms that have done such a good job "eating the world" that they can no longer properly function.
If you really read what I wrote above - there is no "monolith" (and yes, Google is everyone's favorite Boogeyman). AdTech is a primordial pool all kinds of actors, each of which has found a profitable niche to "add value" (or to bullshit partners about "adding value").
