If you look above the unorthodox library/framework distinction, I think the criticism is about birthing new (inadvertently leaky) abstraction layers with new semantics to capture the specifics of the domain. Often with either esoteric words attached to supposedly novel patterns, and/or unconventional usage of existing terminology.
The promise is to simplify and unify things but as noted, such efforts often have the opposite effects.
"Teams are struggling with properly adopting FooTech - our FooBarTool wraps it in a beautiful package and magically solves everything with a single command and one config file"
"We should template all this yaml"
Yeah had so many discussion with senior developers in my life to argue for just keeping things simple, but my god they love abstractions. They are clearly always very smart and understand the code base well. Maybe it’s their intelligence wanting to be more utilised or maybe they are bored and trying to over engineer simple problems

I think this is the main problem.
I don't mind layers of abstraction when they work well and their components compose nicely. Like a well-designed programming language. These can actually be quite fun to work with.
Layers of abstraction where the boundaries between that layer and those around it are fuzzy to non-existent and where certain cases magically work and everything else is a janky mess because it was never designed to work are what give me headaches and want to throw my work laptop out the window on a regular basis.
> magically solves everything
This is the real problem. Too often frameworks/libraries are geared towards making things magic instead of making things solid. Magic solutions are usually very one dimensional. e.g. The Magic only works for a really narrow use case, or at low load. I don’t think this is specifically a problem with “mini frameworks” but homegrown stuff exhibits this more, if only because magic solutions tend to die in the wild when the bug tracker is full of “this only works for trivial case; make it actually work”.
When frameworks/libraries advertise how easy they are to get started, there is often a lot of magic to make it trivial to start and they don’t scale to real projects without breaking through all the magic abstractions.
