They explicitly state 'more useful'. That is the metric they are using, better ads are ads which are more useful.

For example. Until a day or two I did not know the 'MX Master' mouse existed. An advert for this would have been useful.

Useful and obtrusive are not mutually exclusive. Is it useful to have only large companies with large ad budgets peddle a slight iteration to their product line as "the next best thing", while smaller companies with a really great (superior) product don't get the exposure. The smaller company would have lower margins because they invest much more in superior materials, QA, R&D, etc. Where the larger company has an advantage because they invest more of their margin on ads. Note: I have an "MX Performance" and I would not recommend that line of mice no matter what the ads originally said.
