Personalised ads are beside the point. The issue is how they are personalised, namely by building a rich profile of user behaviour based on non-consensual tracking.
It isnt even clear that there's a meaningful sense of 'consent' to what modern ad companies (ie., google, facebook, amazon, increasingly microsoft, etc.) do. There is both an individual harm, but a massive collective arm, to the infrastructure of behavioural tracking that has been built by these companies.
This infrastructure should be, largely, illegal. The technology to end any form of privacy is presently deployed only for ads, but should not be deployed anywhere at all.

Absolutely terrifying.
It makes me wonder how many more things I'll never get to participate in because I've deleted/avoid social media.
I've been thinking about buying a new car, but I'm very aware of how much tracking/telematics they include nowadays... so I decided to search "$manufacturer disable telematics". Every single thread I found was full of people saying variants of "Why do you even want to do that lol" and "Looks like somebody is doing something illegal".
Every time I see stuff like that, I'm tempted to jump in and share a plethora of examples about how tech companies misuse your data, don't protect it properly, sell it to all sorts of dubious actors, and, most importantly, use it for advertising - which I consider to be nothing more than gaslighting to get you to buy stuff and absolutely despicable.
I have to stop myself because I know I wouldn't get through to them, and I would probably sound crazy.
