No, it was a ranting post and parts of it incorrect. Take it one by one.
First point "You still need a debit card to take money out of the ATM". Explained above that cardless withdrawals are almost everywhere now.
Second "Canada did not shut just anyone down". A rant against the government actions I don't know enough about to refute but suspect there's a middle ground. A quick Google tells me the Federal Court later found that the freezing of bank accounts was unreasonable. No response to the China side of the point raised.
Third "You keep paying with cash". What the poster actually said was "I will continue with cash for as long as possible as my main way of payments". Note the word main which indicates he does use alternatives when required.
Finally, he quoted this but didn't respond to it. "I believe cash monitors your spending far better than flashing a QR code on your phone. for some people who just can't manage money, i think cash is better for them." which is a prefectly valid reason for some to continue with cash as a primary payment method.
All in all the post from Patong2021 was just useless hot air.
