I'm not sure which two large corporations you are referring to, but I'll take a guess. My Samsung phone is not linked to my Google account and I don't have a Samsung account. I have no WhatsApp/Facebook/Meta account. I don't use Apple devices or have an Apple account. Possibly the only apps on my phone that have an account linked with them are Telegram and AnkiDroid.
