With the greatest of respect, that's like saying Roe vs Wade was a niche gynaecology case or Miranda rights are just a question of procedural formalities. I am all for getting out of my tech bubble, but mass surveillance is way way beyond just the tech sector.
The existence of warrantless wiretapping brings into question whether the courts even have the right to overrule government actions (a power SCOTUS gave itself back in the early days of the republic). They also circumvent key parts of 100 year old criminal law like the exclusionary rule. And that's just the legalise parts. Not to mention freedom, privacy, democracy etc.
