Among other things, it says that the USPS must prioritize expeditious delivery of "important letter mail". This has usually been interpreted to mean that traditional postal service – first-class letter envelopes – must have top priority, above things like package delivery, contracted last-mile Amazon delivery, etc.
The linked text clearly states that the Post Office cannot do what it is currently doing.
> It shall provide prompt, reliable, and efficient services to patrons in all areas and shall render postal services to all communities.
Prompt, reliable and efficient services does not including refusing to deliver priority, directly-paid-for mail on its routes and instead prioritizing other mail based on a political decision from the top ranks.
The law says that the USPS needs to provide services to all communities. It does not say all packages need to be treated equally. Show me where it says that.
> Prompt, reliable and efficient services does not including refusing to deliver priority, directly-paid-for mail on its routes and instead prioritizing other mail based on a political decision from the top ranks.
That isn't what the statute says. That's your own opinion. Show me where the statute says that.
