Canadian here. Disappointed by the lack of transparency. First, no corporation should be unilaterally shut down without a clear explanation provided, including facts & evidence (which would normally come to light during due process).
Second, if the company is as dangerous as they say, they are doing a huge disservice to citizens by withholding that information and handicapping our ability to make an informed choice about using the app.
Pushing their operations out of Canada also reduces their accountability footprint to subsequent lawsuits or legislation.
This is a weird half-measure and I have trouble making sense of it.
