In this case you go in and request the price and they tell you.

They can't stop you from sharing the price its public now.

No, they didn't tell HiQ. In fact, HiQ is suing LinkedIn because LinkedIn refuse to tell them.

No, they did tell then stopped on 5th product.

LIN gives this information (product price) for first few questions, then if you ask about 5th price they say: 403, no more for you. WHILE IF at the same moment, different person (or you in proxy-ip-disguise) comes and asks for 5th product price, LIN happily (and publicly) gives this information.

And if the person comes wearing googlebot tshirt, LIN drops to knees and give a ..... full-db-dump-job ;) Bing/Baidu thsirts also fit. Source: www.linkedin.com/robots.txt

HiQ simply says: that's unfair you can't decide who is good and whois bad. Effectively LIN bans any google competitor (documented case).
