When you hear the phrase "the Ethereum community", what institutions do you think of first?

(like: companies, organizations, groups, etc.)

I work for Ethereum at the Ethereum Foundation.

That phrase doesn't make me think of institutions at all, I think of users actively discussing Ethereum every day on Discord, Reddit, etc..

If forced to select institutions that would fall under that umbrella, the Ethereum Foundation, ETHGlobal, ETHStaker, Gitcoin, and Protocol Guild come to mind.

Ditto on this. The ETH community are the every day users + the projects that we interact with.
