Generic Problem with LIGO's Gravitational Waves

LIGO's "discovery" of gravitational waves is doubted these days but mainstream doubters wouldn't agree that a generic problem makes the situation much worse. Unlike special relativity, general relativity is empirical, not deductive. If so, none of its predictions matter, including everything it says about gravitational waves. The models Sabine Hossenfelder criticizes are actually metastases from the primary tumor, general relativity:

Sabine Hossenfelder: "Many of my colleagues believe this forest of theories will eventually be chopped down by data. But in the foundations of physics it has become extremely rare for any model to be ruled out. The accepted practice is instead to adjust the model so that it continues to agree with the lack of empirical support."

Sabine Hossenfelder (Bee): "The criticism you raise that there are lots of speculative models that have no known relevance for the description of nature has very little to do with string theory but is a general disease of the research area. Lots of theorists produce lots of models that have no chance of ever being tested or ruled out because that's how they earn a living. The smaller the probability of the model being ruled out in their lifetime, the better. It's basic economics. Survival of the 'fittest' resulting in the natural selection of invincible models that can forever be amended." http://www.math.columbia.edu/~woit/wordpress/?p=9375
