I have never once clicked a "sponsors" logo, but I have definitely seen a logo I know and probably thought better of the company for it - baring GloboMegaCorps that I have long since calcified my opinions about.

Though, if you want to sponsor me GloboMegaCorp, my opinion can definitely be bought.

We do a little bit of this with depot.dev and it doesn’t have meaningful conversion.

But, I do think it helps awareness as we do get some folks that tell us I saw you on this repo or that.

We also do it to support projects we think are neat/useful to others even if we don’t use it.

we mainly do this because it can just help with getting PRs approved if we want to fix an issue in something we rely on (and it is nice / we can list as a perk), and a little influence can be very valuable if we want to give feedback on a project's direction. doesn't do much on the growth side as far as i'm aware, for us at least.
