I hope my drive-by PRs don't come off in the same way.

For example, as the simplest no-description, no-comment example, when I see typos or wording errors in text on a random blog I check if there's a direct way to contribute - to GitHub edit and submit a PR, and when there is, I do that.

There's nothing for me to say or describe, really, and it's not like I interacted with their project or community before or even plan to after. (Sometimes I do look into the issue tracker etc depending on the project or website. But that's beside the raised concern.)

I see it more of a collective and open collaboration. But that's not necessarily visible on the receiving end.
