good question. As you say, you see this on startup landing pages all over the place, and I have done this for clients in the past, too. But as logos are usually protected by copyright, I think the only way to get this legal is to ask those newspapers for written permission. Some companies have guidelines for logo usage on their websites, too, maybe check that first.
On the other hand, as there are no conflicting interests and you are even linking to their website (maybe?), I would probably just put the logos up and see what happens. You can ask for forgiveness later :)
Anyone in the up.front crowd who knows more about this? Sounds like a topic for a lightning talk :)
Cheers,
