I get very suspicious of things I see advertised too much. It either implies that the company has way too much money and is blowing it on ads, implying some predatory monetisation, or that it's spending money it doesn't have on ads, which means it's going to either implode in a few months or have to jack up prices.

Remember: "Ad-supported content" isn't really ad-supported, it's supported by the customers of whoever's buying the ads.
