Why Options To Clean/Uninstall Device Essentials

Hi everyone

I am new here and this is my first time here and I've jumped on board to ask this question to you all.

I do hope someone in the community may be able to direct me, as am not sure "yet", if I will get an answer from our app owners.

Anyway, why are we given the option to uninstall our devices systems applications.

Isn't that just a no no?

I hope my question isn't as silly as it sounds but I need enlightenment here, as I have a lot to learn.

Looking forward to any repay :)

Is this for ccleaner android as well? If so i'll move it to the appropriate board
