Aren't you carrying the water by owning their products?
Carrying water is a little more than just ever monetarily supporting them.
That being said - I own a Fender and some Disney stuff, but they were all bought second hand. I've never bought anything new from Fender, and I can't recall ever buying anything new from Disney.
"Carrying water" has an implication of "Doing the work for", and in this case it's "arguing for big businesses repeated manipulations of IP law".
