I use React every day and haven't starred it. I star random stuff I want to come back to later (like Vue).

I use stars that way too - as a quick bookmark. Thinking about it now I don't actually star things that I'm using.

(have used both React and Vue a lot, haven't starred either one)

Same. Star is sort of like a bookmark for me to revisit them at a later time.
