Unfortunately, without concerted effort, the public will willfully reject an alternate history if it's more nuanced. Exhibit A, who invented the telephone?
I don’t know what skin in the game Canada has when they passed a resolution recognizing Bell Graham as the inventor.
Honestly to me it looks like there is not a clear answer. You can pick either of them you want, draw an abitrary line in the sand about what a ‘telephone’ really is and use that line to defend your choice.
Any rational argument on the topic will have to start with both parties agreeing on what a telephone is first and then looking at the two parties to see which invented their agreed definition.
