I actually find alternativeto so useful that I usually just go directly to it instead of my search engine when looking for FOSS alternatives. Having to go to the alternative page before clicking the official site link is a small hassle compared to finding what's the official from name search, but it used to be better when the description page and the alternative page were the same. If I were to guesa, they probably changed because it would be confusing for people searching for alternatives and finding the software description.
