Why are Minecraft mods so hard to install?

Mods are written by third parties and are (as far as I know) free, so you’re not buying the mods, you’re buying the game. Most people create mods for fun, and it’s more fun to create a mod than it is to make the mod easy to install. They’re often hosted on download sites that have deceptive ads all over them too.
