That Wikipedia article is flagged as needing 'additional citations for verification' and they're not wrong. Specifically, that claim about knowledge of the Meteor programme is completely unsourced.
The same article says that development of what became the Ta 183 began in 1942, when as far as I can see Meteor development was at the stage of working out number of engines: presumable exactly the same sort of calculations as were going on in Germany and ended up with the Me 262.
