Racism or other forms of discrimination apply to a protected class of people; any group sharing attributes beyond their control (bearing dark skin, a particular place of birth, a religion, etc)
Russians are a protected class. Vladimir Putin, the evil individual who ordered an unprovoked war on Ukraine causing thousands of innocent deaths, is not a protected class.
While I have seen racist uses of monkey imagery towards black people, never have I seen it towards Russians. In conclusion, there is strong implication that this meme targets the latter, not the former.
None of the good stealth games I know actually force stealth. You just get scored based on the amount of chaos, and enemies gain varying amounts of information off your actions. It doesn’t necessarily change to a firefight just because one guy saw you.
If the shootouts are the better part of this game, not to mention the stealth takedowns looking pretty bad, it probably makes sense to shift this way.
