The top players, intent on proving they are the best on an international scale would welcome the use of the combined dictionary at all tournaments. Many others see the advantages of one worldwide dictionary. Those of a more parochial bent do not see any point in changing the dictionary. They do not intend to play abroad and do not want to have to learn any more words. Some also do not want to have words from another culture within their dictionary, though it's questionable whether OSW or TWL respectively, truly reflect the UK or North American vocabularies.
Feelings run very high on the subject.
Even if the Scrabble players were to agree on a worldwide lexicon there are commercial interests to be satisfied as well. Hence the 5 organisations would need to agree that such a dictionary was desirable before it could be produced, so far such agreement has not been reached.
