Ok... since I like this stuff, I went ahead and went down the rabbit hole you've opened to see what's really up so we can put this to rest.
That 6.75M float number on Finviz is in fact incorrect. Someone made a mistake. Its off by a factor of 2. They were confused since each ADR share that is tradeable... represents 2 shares of the ordinary stock.
So all these web links aside... lets go straight to the source.

13.5M shares were offered during the IPO.
As you can see.... 13.5M of the ADR's (they call them ADS's) were all that was offered.
Scroll down to page 181.
"Upon completion of this offering, the closing of the Concurrent Private Placement and the issuance of the Anti-Dilution Shares, we will have 13,500,000 ADSs outstanding, representing approximately 17.7% of our outstanding ordinary shares or, if the underwriters exercise in full their option to buy additional ADSs, 15,525,000 ADSs outstanding representing approximately 19.8% of our outstanding ordinary shares. All of the ADSs sold in this offering will be freely transferable by persons other than by our “affiliates” without restriction or further registration under the Securities Act. Sales of substantial amounts of our ordinary shares or ADSs in the public market could adversely affect prevailing market prices of our ADSs.
Prior to this offering, there has been no public market for our ADSs or our ordinary shares in the United States, and although we have been approved to list the ADSs on the NYSE, we cannot assure you that a regular trading market for the ADSs will develop. We do not intend to list our ordinary shares on a trading market in the United States."
Now in absence of any subsequent filing with the SEC, which there has not been as of today... this is pretty much the float. 15.525M
As you can also see... go to page 13
Ordinary shares to be outstanding immediately after this offering, the Concurrent Private Placement and the issuance of the Anti-Dilution Shares
152,766,494 ordinary shares (corresponding to 76,383,247 ADSs) assuming no exercise of the underwriters’ option to purchase additional ADSs; or, 156,816,494 ordinary shares (corresponding to 78,408,247 ADSs) assuming full exercise of the underwriters’ option to purchase additional ADSs.
So... 76.3M to 78.4M is the total # of shares outstanding.
As of June 14th, the latest report of open short interest as released by the NYSE... there were 5.87M shares sold short. The WSJ figure is accurate.

So 5.87 divided by 15.525 is 38%.
Thats your short interest, or pretty damn close.
If someone is inclined to short it today, the current borrow rate is about 26%. It was as high as 60% in early June.
So... Regarding Igor and his Tweet... did you notice in that thread several people called him out on his numbers (just like I did). He made no effort to explain himself nor did he admit his mistake. So whatever. But no stock that has only a 6.26% open short interest sports a 42.37% borrow rate. An "expert" would know that. Maybe Igor was hitting the sauce that day.
