ELI5: Why are some shows edited when shown on Netflix?

I'm watching the third Family Guy Star Wars episode, and notice that some little pieces are missing. 

The first is at the beginning when Stewie and Roger are talking. Roger says there's still a hole, but no trench on the second Death Star.

In the original, Stewie reprimands and cautions him that he'd better fix it. On Netflix that line is cut.

Why? It doesn't seem like it's a line that would need cut for copyright infringement, and netflix shouldn't need to cut for time.

Netflix doesn't edit the content, they just get whatever they get sent. Very rarely, the version is slightly different than the original version that aired on TV. Each one would be a unique case, and almost never would the network that owns the material say why changes were made.
