There are many sentences, most are titles, that have the before nouns when they seem okay without it. I assume it is added to over-define them but not very sure.

Here is a title that uses "the" excessively:

GOVERNMENT OF THE PEOPLE, BY THE PEOPLE, FOR THE PEOPLE

"People" by itself is defined and doesn't need an article.

And here is another title that has the same issue:

About the Java Technology

So, why it is added?

Good question. When you say "the people", rather than just "people", the meaning is something like "all people" as opposed to "some people". That is,

Government of people, by people, for people

would mean that the government is made up of and is intended for some people. That's not a very effective or inspiring message. I would also say that "the people" usually means "the common masses", as in, ordinary, non-elite people.

Also see definition 4 in Merriam-Webster, https://www.merriam-webster.com/dictionary/the :

used as a function word before a noun or a substantivized adjective to indicate reference to a group as a whole

// the elite

As for "the Java technology", I think that's more like definition 2a1 in Merriam-Webster (same link as above):

used as a function word with a noun modified by an adjective or by an attributive noun to limit the application of the modified noun to that specified by the adjective or by the attributive noun

// the right answer

// Peter the Great

"Java Technology" doesn't really have a different meaning from "the Java Technology", but I think the the emphasizes the fact that it is Java and not some other technology.

The answer is - Emphasis

Example one, with the emphasis -

GOVERNMENT OF THE PEOPLE, BY THE PEOPLE, FOR THE PEOPLE

The article "The" is used to signify that the Government that is made by (non-political/common) people, and only for people (and no one else). 'The' is talking about specific people. (This means people like the reader of the message)

However, without the emphasis -

GOVERNMENT OF PEOPLE, BY PEOPLE, FOR PEOPLE

This is true for any government. As far as I know, there are no governments for aliens, by aliens or of aliens. Every government is of some people, by some people, and for some people.
