Other commentators are rightfully pointing out that this information is open public in other jurisdictions, and that Albertans' information is almost certainly already being shared and sold.
I believe the reason why this has become such a large news story is the tension between Alberta (and the west) and the rest of Canada. Alberta has rising separatist sentiment, a premiere who is extremely popular in Alberta and extremely unpopular outside of Alberta, and is on average more right wing compared to the rest of Canada. In both the media coverage and popular sentiment, this incident has been used to show Alberta and its government in a bad light, despite it not having anything to do with the party currently in power.
As long as it makes Alberta look bad it's an excuse to attack Danielle Smith and the UCP, and Albertians in general. Other Canadians eat up negative Alberta news like nothing else, and the media will no doubt provide them with the type of news that they crave. If this happened in any other province it would get 1/10th the coverage and outrage. Instead you have people online calling for Smith to face prison time for something she was not involved in. The media gets their views and the people get their ragebait.
Smith was friendly with Parker.
Attended his wedding, did softball interviews with his wife who worked for a right wing media site.

The reality is more the complete opposite. People from not-Alberta care about their own provincial governments and issues and don't really think about Alberta at all.
It's the media and government in Alberta that is encouraging this notion that "Alberta is under attack" from others because lazy grievance politics works and it's a good distraction from scrutiny on the failings of the Albertan provincial government. You see the government of Quebec do the same thing, blaming Rest of Canada for all their woes, wrapping themselves up in the provincial flag, etc etc.
Don't fall for this stuff.
