All merchandise is commercial. Do your kids wear a Nike swoosh t shirt? Okay on an iPad? Love Lego? What the difference if it's a Microsoft football or new relic slingshot (all things I see from where I'm sitting)?
2) Some of us in fact do avoid wearing logos. Nicer (and not even that nice, necessarily) clothes, bags, shoes, et c. tend not to have them, or at least make them very small. Logos for something other than the company that made the item would be even worse. Large logos and legible clothing more generally signal things I’d prefer not to signal, so… I don’t. Freebies in that category get worn around the house or as a base layer.
That's me
Branded Lego is probably the most durable chotchki you’re going to find.
(Now it's kind of boring because they sell them online, before those were exceptionally rare as they were basically only sold directly to Maersk.)
Nike? No, iPad? No, Lego? No, Not sure what the other things are.
