Why do you trust Apple with them? What guarantees Apple will not do evil?
If, at some point, they converge, I will trust Apple as little as I trust Google, but it's absurd to pretend they're the same thing, today or to "what if" yourself into knots.
Google is absolutely an evil company, head to toe, that is aligned against you. Trusting them with anything is almost as stupid as trusting Meta.
You should never really trust a business with your information. At the end of the day all they care about is making money and most customers have no interest in the business making more money, so you're never really in alignment.
Thinking they're the same, or will do the same things, or playing slippery slope games is really silly and/or a complete waste of time and energy.
It's not absurd whatsoever. Apple and Google are oftentimes asked to make the exact same concessions, and in many cases (see: push notification backdoor) they do exactly the same thing: https://arstechnica.com/tech-policy/2023/12/apple-admits-to-...
Neither Google nor Apple have any real accountability at play. The same mechanisms that demand Google to surveil users are being accepted by Apple too. The "ad business" canard is (and always was) a distraction.
