(My point is those two tend to go hand and hand: higher percentage of unwanted traffic originates from authoritarian lands still engaging in 19th century style barbarism.)
Just imagine living in America in 2003 with 9/11 fresh on everyone's minds. Were you there? Do you remember the mindset of adult Americans in 2003? What did the US military do in 2003? What did the average CNN-watching American feel and want? I remember well. We wanted to bulldoze Saddam Hussein and his "Axis of Evil" because terrorism. We wanted to raze Iraq to the ground as revenge for "harboring terrorism" and "WMDs" which were about to be unleashed upon our friends. Americans were in a complete frenzy, psychosis, and out for blood. Do you remember? I remember soldiers wanting nothing more than to "take out those stupid rag heads." Did the occupation ever end? Did Iraq have anything to do with 9/11? Did anyone suffer the consequences of the invasions back in America besides the Americans killed overseas? Do you think Russians are not actively being brainwashed by their government to support a war like the Americans were for their wars? Think again. The media is more powerful than ANY WMD because it perpetually and incessantly corrupts the minds of its viewers.
There was a lot of support for that war, but that support was far from unanimous, especially on the grassroots level. I do not remember any supporters of the war who I knew personally who wanted to raze Iraq to the ground and, as I recall, the antipathy was more directed at the Saddam regime and not the Iraqi nation.
Your overall point is valid, whitewashing enter nations with a single brush is inaccurate and unfair. However, you are doing the exact thing you are trying to criticize.
Whataboutism aside, those events are not 1:1 relevant to what is going on today. Turkey maintains an indefensible invasion of Cyprus, and engages in acts of wargames by frequently flying fighter jets over Greek airspace, constantly taunting them and threatening to take more of their land, laying baseless claims to Aegean seas, and Russia maintains an indefensible invasion of Ukraine, and followed a very similar plot.
Missing in either of these two situations was 16 other nations imploring the country soon to be invaded to comply, and the largest act of terrorism in the modern world.
Companies find it easier to simply block or restrict access from certain countries because it's "more hassle than it's worth".
When you as a company (especially financial one) is serving thousands or millions of customers you must have/rely on statistics with a heuristic to detect fraudulent or an abusing customers. Also you have to decide whether you will have any troubles by giving a loan to a particular person. Such heuristic systems are scoring using hundreds (if not thousands) parameters like age, marriage status, sex, whether you believer or not, what is your smartphone (e.g. according to bank's statistics Android users are tending to not return credits more ofter) and so on…
What’s most important: banks will never disclosure what has lead them to their decision like to decline in a credit line. Just to avoid further cheating with their heuristic systems.
I believe the author had become a victim of such heuristic which is likely had detected something unusual, then it considered his profile + recent connections (perhaps he had specified a different country than Turkey), and finally «free tier» had added some alarming amount to scoring. Otherwise I can't explain why support had wrapped up a chatting so quickly and unfriendly. For me everything points out on that there was a distinct reason for them to cease his account and they won't like to disclosure it in any way.
