Yes. Not a rando online petition: “we have succesfully escalated complaints on this problem to consumer agencies in France, Germany, and Australia, and have brought forth petitions for new law on this problem to various countries.”

Petitions from verified voters are powerful. Triply so if done in person, because the infrastructure that can collect signatures in person can also e.g. back a primary challenge or plebiscite.

Has legislation been created as a result of that awareness?

And the vast majority of their awareness actually came from a failed counter-campaign by the opposition.
