Oh amazing, could you link me to that person's post?
On your second point, my hesitance isn't so much about whether friendlies are "official" or "unofficial" (they appear to be the latter, which makes sense), and more whether they constitute a "competition" or not.
My common sense understanding of the word "competition" is that it is more or less synonymous with "tournament" or something like that (i.e. multiple gamers between more than one team with an overall winner). It wouldn't, to my mind, describe a one-off friendly game.
The FIFA eligibility rules appear consistent with my understanding, because they distinguish "competition" from "matches" on multiple occasions (see for example at Article 5 29.4 which mentions "football trials, training camps, matches, or competitions", thereby distinguishing the two, as well Article 9.2 a and b, both i and ii which all refer to a "match in an official competition").
On that basis, it looks like a friendly match ought not be counted as an "unofficial competition", but if someone in the know has said otherwise I'd be very interested to read it!
