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.
> We use the combination of your Facebook and LinkedIn data plus your About Me and Photos to ensure we are building a balanced, high-achieving and diverse community. Our screening algorithm looks at indicators like social influence, education, profession, industry, friends in The League, number of referrals you've made to your network, as well as supplemental data like what groups you belong to, events you've attended, interests you list, and preferences.
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 use LinkedIn. I haven't used it in years, now I'm back because that's where the headhunters are and where I can probably find a job. After I'll find new job, I'll switch to zombie mode again and won't use it until I need it again.
So yeah, the reason I use LinkedIn is to not miss a job offer. I don't have a reason to use FB thought.
