Many of the links are dead because they expired, which is probably a good thing.
(Sigh) Not for me and my poor 3000T series friend, who is missing his one-time demo licence. I fell so sorry for him, even bought him MSO licence to cheer him up, but he is still so sad
But seriously - for example, Google Drive link can be set to long-time access, right? And, if i remember correctly, some russian guys posted here links to their local file-sharing service ("Yandex", if i am not mistaken) - i think its link could be set to long-term access, too. Although, it's understandable if people do not want to post links due to legal reasons, i totally get it - if this is the case, i'm really sorry for being needy (but still have a hope for a some good soul, though).
Edit: There is a hope for this world - thank you from the bottom of my heart, a good soul
I am not sure if it will help my 3000T to feel better (not quite sure, but i suspect A and T series are different), but i definitely ask him shortly, how does he feel.
