Advertising corrupts. Ad-tech corrupts absolutely.

The reason is the cumulative impact of two things:

1. Algorithmic optimization of results for ad click-through rates, and

2. The scarcity of space for organic results on results pages for queries with commercial intent (because of the large amount of space given to ads). The high value of the clicks on those pages (sometimes $100+) drives marketers to focus disproportionate resources on SEO tricks and gaming to show in one of the few spaces left on the front page.

A search engine with ads and ad-tech tracking cannot work well for consumers in the long term. Google is now an ad-tech company, not a search company. It employs 3x as many people on advertising as search.

[Edit for clarity] It makes sense in this context to programmatically re-write titles to optimize conversion, rather than consumer experience.
