Why not? They, like anyone else traveling or doing business internationally, should decide which countries should be avoided. They can use whatever opinions or judgements they want. It is possible for a huge international corporation to have some sway on a country by not doing business there. But that's not always a bad thing. I'm more afraid of bad governments never suffering from bad decisions than this slippery slope.
Why not? If they can decide which speech is tolerated on their platforms and which isn't, then why not this?
If you are accusing me that I'm preaching and not following my own words, that is a big assumption on your side.

Of course, all things above are not simple. There is the prisoners dilema "if not me, then someone else will do it", and "if it is me, I can prevent even worse from happening", but there is also the "slippery slope" where making small concessions leads to more and more concessions. So, everyone make there choices and we all leave with the consequences.
You're right that this is beyond the scope of Google in the same way that it's beyond the scope of any individual. But together humans can slowly influence other humans and doing the right thing might be a tiny influence but eventually these might add up.
Google restarted business in China around the same time it was able to bring the BeyondCorp initiative online.
It isn't a case of 'caving to pressure', but of 'complying with the law', since the apps are available in other countries, just not in Pakistan, where they are deemed blasphemous, according to their laws.
