As long as the add-on is useful and harmless*, we should just use

If you choose the installation without sponsors, there will be no
adware/spyware in your computer, just like mine, very new and
clean.
MsgPlus only have adware/spyware in its installation if you choose
to install "With Sponsors", its just a matter of fact that you
should read the installation process carefully and not just click
"Next, Next Next Next".
*harmless denotes no
spyware/spywares.
