A very prominent businessperson being held for allowing her company to commit fraud and violate US sanctions in a country that has an extradition treaty with the US is not the same thing as a country "suddenly" detaining two expats, in an immediate and obvious response to the previous lawful detention. The two Michaels weren't even charged with anything after they had been detained, imprisoned and interrogated for 5+ months! Meanwhile Meng Wanzhou was able to continue living a relatively comfortable life under home arrest. It's not fair to suggest that the average person - Chinese or not - will just randomly be arrested and imprisoned for months in Canada, with no charges filed whatsoever. The same thing happens frequently in China.
