Starting up your PC, exiting your home, going to sleep, and starting your car are not examples of entertainment. It would not be acceptable, in my opinion, to put ads on anything that is not entertainment, or a website.
your pc can be used to play video games.
videogames is entertainment.
therefore, putting ads on starting up your pc is an example of entertainment.
also there's lots of ads on websites
which sucks but yeah
at least they don't interrupt anything
infact
let's look at badspots famous quote about going to a free barbeque and having the host throw poop at you
but obviously if it's free you can't complain about it right?
RIGHT?
