Why must people update their stuff just to make thigns worst?

As we all know we the users have to update our client, game, version in order to still use the service provided.

But the big question is why msut they create a tiny update for their so called bug issue or to make it looks more cool just to messed it up even worse?

For example, the new dota 6.54b well it is said that they fix the various bug detected in 6.54. But the truth is, the frst game itself already have bugs (BIG SWT).

And why all this happen? Just because some one said oh well lets make the character attack more cool or the skill more cool.

Same goes to gg client. Before this, loggin in to gg client take lest than sec. But with the new constatnt update, there is:
1. lag everywhere
2. some room cant work
3. client cant go in
4. is even more laggy to go inside the same room
5. they remove the function that allow you to listen that your friends already created the game
6. loading the home page is even longer.

The other bad example of updates is our beloved messenger
in the l days msn 3.0 - 6.0 we dont have dat much peroblem as file cant be delivered or cant sign in
But with brand new 7.0, some days we can't log in and some people cant receive the file after a damn long time transfer swt

This lead to one question, why must people itchy hand change something good to a very bad thing but loosk slightly cooler?
