There's a difference between "following the law" and eagerly participating in state-sponsored censorship.

There's also the fact that, in countries with basic human rights codified in their constitutions (i.e. most of the Western world), companies like Apple, Google, and Microsoft make a lot of noise about protecting the rights of their users. But in less free nations, they tend to silently flip to the other side and go out of their way to appease the governments of those nations, especially wealthy ones like China. Hence the ease with which their services are manipulated in those countries.

Not all the lawful methods of making money are morally acceptable and people should refrain from using them.

IMHO this is an example of that. Morality is probably subjective and you might disagree on this example but I'm sure you can find others.

Yeah and Harriet Tubman should have been arrested for illegally smuggling stolen goods /s

It's not such a big deal unless you happen to be in the business of making politically relevant information available.

Helping a dictatorship shield itself from criticism and spread its propaganda is not quite the same as compliance with, say, food labelling rules.
