I'd rather not have personalized ads because I'd rather there not be an incentive to harvest my data to leverage for personalization.

I may be an outlier since I generally try and turn this stuff off everywhere. I also pay for a lot of ad-free content that I like (Stratechery, Stay Tuned with Preet, Persuasion, etc.).

I think the incentives from ads are a corrupting influence in building stuff that users want. I think the 'personalization is good for users' argument is often just a rationalization.
