Given the response to Amazon doing so is "how dare you complain about Amazon using these loopholes, it's their fiduciary duty to bilk the government out of all the money it can", I don't think there would be widespread publicity to other companies using loopholes.
Instead we'd have people like you trying to shut up anyone talking about them.
The first step is recognizing that there's a problem.
> If the problem people have is with tax subsidies in general then isn't the government the real issue here?
Maybe the problem people have isn't with tax subsidies. Maybe their problem is who the subsidies are being given to? People are realizing that Amazon isn't a good corporate citizen, and I don't think anybody thinks Amazon needs these subsidies.
Lots of shady tax related shenanigans happen in NYC, particularly in real estate development. Sometimes they get called out, and sometimes they go unnoticed for years/decades until new information draws the public eye to them.
