I don't think it is fair to bash Coinbase just because they have a similar name to CoinLab. The link you cite seems to conflate the two as the same thing, but they are actually different, and it is just plain dishonest to make a mistake like that and not fix it in the article. That might be libel?
And your assumption that they're different is based on what? (Tho I do chuckle at the implication that equating them is libel. To which one remains an unanswerable question).
Global Bitcoin Stock Exchange (GLBSE), Mircea Popescue's Exchange (MPEx), both have exchange in the name, therefore they are the same thing!
Really, are they related in any way other than they both have something to do with bitcoins and their name starts with Coin?
Obviously equating them is insulting to Coinbase, which provides a service for exchanging bitcoins and USD, whereas Coinlab does ... something?
