I think the motivation is important. Many FOSS projects are sharing something the author considers useful to the world, as a way of making it better in a way that they know how. Its a lovely gift and I'm happy to know about it.

Others are there to promote lock in to some cloud service, or increase the authors rep as a 10x hacker and those are skeevy because the author is skeevy and did not have joy in their hearts.

All corporate ads ate the second kind.

Unfortunately, it's a useful thing that people have used to prey on our inquisitive simian brains.

Personally, I'm in favor of doing things like banning billboards &c, but it's hard to draw a line on banning advertising in general.

I think I'd be willing to extend it to all forms paid advertising that you are forced to see in the course of doing something else.
