Oh, this seems to be a pretty misunderstanding: Sure, "Oy", "Ltd.", "GmbH" etc. are similar legal forms in different jurisdictions. "Jolla Oy" (in Tampere, Finland) and "Jolla Ltd." (Hong Kong) are different legal entities (as you also pointed out, already), but their exact relationship is unclear. But unfortunately there seems to be no fresh information on the proportions of shares held in "Jolla Oy (FI)" and / or "Jolla Ltd. (HK)" beyond what has been discussed on TJC (see also bullet list in comment to next answer there). I originally assumed, that your post #115 was not solely about the different names for similar legal forms in different jurisdictions.
