This is very irritating and so customer unfriendly .. I wanted to see a document from Ovum(I found the title through Google). After a fairly long registration process, which included giving my address, whether I was an ‘incumbent telecom operator’ or a ‘new entrant’ – I finally find that the document is a part of their paid subscription!
(If I had known it was a paid document, I would not have signed up for it in the first place)
Not very customer friendly .. and now I guess I am stuck for life with emails from Ovum!
