Why is the moon no longer called a planet?

It never was, not in any culture. This is because the nomenclature evolved before anyone knew the other planets were actual solid (or, well, gaseous) balls rather than points of light.

It is a planet from a philosophical perspective but not the scientific perspective..
So before science was mature, it was probably called a planet.

Back before we knew of other planets there were three* entities in the sky, the sun, the moon and stars. The sun and moon are pretty unique in the sky, it's hard to get them mixed up with anything else. Stars were a different matter and came in two varieties, (fixed) stars and wandering stars:

- (Fixed) stars are the stars we know today, static points of light that barely move relative to each other even as the night sky itself moves.

- Wandering stars were "stars" that appeared to move across the night sky. These are what we have since identified as planets, comets and such.

*in some early cultures clouds were also treated as part of the same sky.

because it has completely submitted to earth's gravity.
