No more or less absurd than Microsoft being forced to advertise rival web browsers.

A bit more absurd. A closer analogy would be if Windows was required to ask you on first startup if you wanted to install Linux (i.e. advertising a competitor to the thing you're using vs. a thing bundled with the thing you're using).

Not only on the first startup, but on every use.
