Don't confuse the many voices of a crowd with a single person's fickle view. If you can track an individual person or organization who changes their mind 'every other week' then more power to you, but unless you're performing that longitudinal study you are simply seeing differential levels of enthusiasm.
I get what you mean but they're all over twitter, its not random levels of enthusiasm, follow a few heavy llm users who tweet a lot and you'll see what I mean.
