Google core business is ads. It is not the same.
Whichever one you think is worse is really just a reflection of your own personal values. I value computing freedom above all.
So perhaps you should consider switching to GNU/Linux phones.
Apple’s core business is selling hardware. Their services revenue is not even close to their hardware revenue.
You buy a phone, and you're forever forced into buying only their peripherals.
You could say that there are Apple devices that do not work well or don’t work at all without another Apple device, and off the top of my head I would say the only ones are the Watch and the HomePod, but most alternative devices work fine with Apple ones, e.g Chromecast, Garmin watches, Google Home hubs, etc.
And even so, the same could be said about Android only features and devices, e.g. Samsung Watch doesn’t work without an Android phone, Google Earbuds are feature capped on iPhone, etc.
IMO, if we are looking at rent seeking behaviors, Google shoving Gemini down the throats of Google Home users, with no chance of rolling back if they don’t like it, is way worse.
Did you get rid of all your micro USB cables and devices once the transition to USB-C began for Android?
You're literally describing Apple's business model.
Google most profitable business line is ads. They profit from literally knowing everything about you, then selling access to that to ad bidders. Apple makes the most money from devices. It is not the same.
Then why is it that they advertise? We just last week had a thread about how the Apple app store is making ads blend in more with organic results. So not only are they advertising to users (which admittedly was news to me), they are engaging in dark patterns to make those ads more enticing. It doesn't seem like being locked into the Apple ecosystem (and paying their tax on hardware) is actually benefiting the users.
