Obviously that's not the main thing to learn from this crisis ffs.
1) We have too many eggs in one basket in the telecom/internet sector
2) Our economy is too reliant upon technology now
3) Going completely digital with currency is not feasible because our economy can be turned off like a lightswitch
As far as the criticism against Trudeau is concerned, I don't know how much of this should be pinned on him. I don't remember whether Harper was opposed to massive telecom mergers, in favour of them, whether he was completely in favour of moving towards a system where we're all completely reliant on tech or not, or whether or not this was even something that he was talking about. Maybe he was oblivious. I dunno, so I won't weigh in until some of those questions are answered.
Right now, statements to the effect of "this is all Trudeau's fault" are unsubstantiated, although that may not end up being the case. Maybe Harper was just as guilty or more, I don't recall.
What we absolutely can say about Trudeau though, is his main concerns about the internet and currency to this point have been:
1) the gov't needs to control the flow of information
2) the gov't wants to move towards a digital currency
3) the gov't cannot be trusted with the amount of power they would exercise over digital currency, so we still need the traditional alternatives.
All 3 of his main priorities seem pretty fascist in nature, without any concern whatsoever for the risks that they pose... Go figger.
