I have bought a few things by clicking on Instagram ads and enjoyed it. I choose to allow all apps to track me because I really dislike irrelevant ads. Ads will get smarter in the future, and I think this can be a good thing for the consumer. I’d really like to understand what the issue everyone on HN seems to have with this is - to me, this seems more of a personal preference (being privacy-conscious), rather than some sort of a fundamental issue that is bad for users (it’s not).
