If it's a huge problem psychologically for you, maybe you can just take the following 5 years or whatever time you estimate you will be using the product and calculate that into the base price to make your decision.
Adding advertising into the mix almost always makes the incentives align more poorly with the customer's interest. For example, the refrigerator manufacturer now has an incentive to increase food spoilage to increase ad conversions.

So you want to pay them to show you ads in the hopes that that means they don't stop supporting your refrigerator? What does that even mean? They're not going to extend your warranty.
Think of it like working conditions getting increasingly poor and abusive year over year, while your salary stays fixed.
It matters not because the deals are increasingly shit and abusive, but also because them being much better is within most of our's living memories, and there's no actual reason for things to go this shit, except a supplier-driven market fucking customers over because they can, and race-to-the-bottom mechanics preventing any single vendor from reversing course.
