I think it's simply fair to provide context and compare with other countries. While the US immigration process sucks compared to many countries, it very likely is in the top half of the world - most countries are simply worse.

I've lived in places where you have a zero chance of getting permanent residency, let alone citizenship. Even if you marry a citizen.

A friend of mine lives in a similar country. On paper there is a route to permanent residency, but no one gets it unless they're well connected to a senior government official. Lots of people living there for 30+ years who have to renew their status every few years.

In parts of Switzerland, your neighbors will vote on whether to grant you citizenship.

Of course - it is fair to criticize the US immigration process - particularly in regards to Chinese and Indians. It's also perfectly fair to be grateful that their is a path.
