I share the same sentiment towards corporate. I'd also remove/conceal big brand logos like this when I can, or I'd shop for things without visible logos to begin with.
I do, however, like to wear band merch. Bands that are just as happy to see me as I'm happy to see them. People I can go and talk to at the merch stand. People who, funded through merch and shows, will have the means to record another album.
