Money could be spent on SEO and useful visibility. Instead it is spam, and wastes my time and resources. It has no value to me. I have never and will never purchase anything advertised to me. I view any product with an advertising budget as massively inferior to any other in the same space. Any consumer product in the present market only has 20%-30% of the cost the end user pays going to the company making the thing. If that company is spending half of that money to advertise, the product manufacturing, packaging, and logistics costs them ~5%-7% of what I am paying. The other companies in the sane space can put ~15%-25% of what I'm paying into the product. So simply avoiding anyone that advertises results in a potential of three to five times more product for my money. Any company than needs to spam market to the world is doing so because they can't survive on their reputation or merits.

Plus, my data is a fundamental part of my person. Owning a part of me is the latest form of theft of autonomy. I prefer to call it digital slavery, and those collecting and selling personal data as digital stalkers. It is a means to manipulate and alter access to information. This isn't 1999; no one is using this for banner ads in a trillion dollar industry. Search engines and the internet are no longer deterministic, you have no way of checking and balancing the echo chamber you exist within.
