Whether or not that tit-for-tat behavior leads to a net benefit for the US is up for debate. But the fact the EOs cite "national security", "privacy violation", etc. as the main reasons for banning makes you wonder "are those the real reasons behind this ban?" If they are, then questions raised by OP's article is perfectly legit, and makes the ban look either misplaced or hypocritical. If the ban really is tit-for-tat, what's stoping the EO from just saying so? Honestly, this whole situation makes the White House/Department of State look like they don't even believe those allegations themselves, which weakens their ground in any legitimate discussion around"national security threat" , "privacy violation" etc.
