Everything but food, clothing, and a place to live are things we don't need. There are countless additional luxuries that make life more convenient or enjoyable. I found out about Instant Pots from ads, and when I finally decided to check it out and found it interesting I bought one. It has significantly improved my after-work quality of life multiple times a month with large reductions in food prep time.
I found out about glowforge the same way and added a very useful & revenue generating tool to a small side-business I run.
So I don't mind a little bit of targeted ads. I don't regard them as inherently bad. I do however believe that each individual should have complete control over the process as it relates to their own personal data.
