I can blame Microsoft. Every other tech company and OS figured out how to make it work and they're not exactly buckling under the weight of legal or political pressure on the matter of flags.
If you had the choice between "no lawsuits at all" and "lawsuits in random months by random countries for things that can escalate to violence and wars" you wouldn't take "no lawsuits at all"?
Even if very few of the lawsuits actually escalate to violence or war, is any risk of violence/war worth it? Ethics would suggest "all my competitors are doing it" isn't a great answer here, either, and certainly doesn't remove the risk.
I can respect the "no lawsuits at all" preference here.
Not playing the game at all is very different from playing the game according to the demands and rules of bullies. The only way to win is not to play, just ask WOPR.
