The phrase associated to or with often creates confusion because writers compare both forms and wonder which one sounds more natural in modern English usage.
In my editing experience, I usually stick with associated with because Google NGrams reports nearly 50M written instances, while 0.5M or less than that amount appears for the latter form.
The odd version often sounds odd because the form has lower written usage and fewer instances in actual writing.
Some writers prefer a superior form or a superior option, although the original question often depends on the source, source reliability, and the purpose of the question itself.
During question editing, editors may edit, quote verbatim, provide a verbatim quote, mention a reference, explain what a citation refers to, and say thanks or BTW while discussing online answers and other answers.
The difference between affiliated, associated, affiliated to, and affiliated with frequently appears in British English, American English, AE, and AE usage, where one expression is used more often because of regional preferences.
