It seems kind of unreasonable to expect Google to never experiment with their algorithm; and unfortunately at its core it is a zero sum game. You might be a winner today but a loser tomorrow.
if your concern is about revenue, sharing or referrals or ad placements or ??? then I would point out that it’s very unwise to build a business whose success is based entirely on the whims of another business.
I think search in general is becoming a very poor way to discover content as it is slowly getting planted by LLMs and also for years has been gamified by SEO.
I think that the right model for content discovery is either crowd sourced by a like-minded community, like hacker news or curated; if the curator or community drifts away from your interests, then you have to find a new one, but oddly enough, this can actually be done within the same framework.
