I think because its based on probabilistic reasoning, and if you can find the right perspective where something looks to be spontaneous rather than ad hoc, then that is indeed the ultimate explanation. And then the reason it looks non-trivial, is because we observe things from ANOTHER perspective.

Why is there a tendency to use the concept of entropy to explain everything from relativity to quantum mechanics.

Everything? I don't think so.

What makes you think there is such a tendency? Please give specific examples.

But I felt hit by the question and focused on the why part.

We have for example attemps for gravity, And also Ariels more general approach, including attemps for quantum logic.

My own personal research is also very much in this direction, and there are parallells to the ideas to abstract physical process as "computations", and when you combined that with statistical inference, there are many very exciting deep possibilites to "explain" things in a very deep way. So even if i agree that this is not mainstream, there exists such a tendencies and the logic behind them is imo sound.

The ultimate vision here is that the LAWS of physics themselves are to be understood as equations to state, ie. as equilibrium conditions. Its then easy to understand the advantages this may have for unification of laws IF successful. So there is great potential.

But to put the finger on the main problem. None so far has been terribly successful and i think its because many attempt to start with an universal objective microstructure, but this unavoidable IMO will cause problems with many things. So I think the "entropic forces" must be understand to be conditional upon observers, and thus - like any computation - relative to the hardware. What is natural or easy depdends on the hardware.

I will leave it there.
