For all the people who is "afraid" , yes , .onion links are used for the dark web but you can enter to some links with your normal computer , even Facebook and NewYorkTimes (and i think twitter too) have a .onion link and you cant get inffected with those links
Whats the point ? - Tor its an anonymous red who brings more privacy to the users , tor use multiple IPs for hide your real one and actually encrypt your data so the point of this its that , more privacy who its always welcome
sorry if this its a shit explanation but english its not my main language and idk how to explain tor for dummies
in many words : yes , you can use this link on your main computer without problem its not ilegal shit
