This might be obvious but I think the only way forwards is to disengage in services offered by these mega-tech companies. Degoogling has become popular enough to foster open communities that prioritize their time and effort to keep softwares free from parasitic enterprises.

For instance, I am fiddling with LineageOS on a Pixel (ironically enough) that minimizes my exposure to Google's AI antics. That doesn't mean to say it is easy or sustainable, but enough of us need to stop participating in their bad bets to force upon that realization.
