You grossly underestimate how much some people truly love the idea of highly personalized ads. People who believe they are the best possible outcome and cannot fathom why anyone would have any problem with them at all. That’s who you are asking to dogfood this product, and they would and would find no issues with it.

If you

understand what it is you’re replacing, what you’re replacing it with, and how to use the replacement

then you, almost by definition, are an advanced user.

A beginner should avoid these things, once you are far enough along to understand why you might want to replace one of these things, and form your own opinion on it, then go right ahead. But you’re no longer a beginner at that point.
