Yes, if you want to buy a specific brand you'd need to modify the filter. I'd like it to say pick out the "cheapest lemonade that has lemon in it and no aspartame and scores at least 50% in taste tests" or "the lemonade I drank last time" and just show me that one at my behest!
Simple advertising like branding on the product itself isn't the problem, anyway. It's usually not intrusive nor irrelevant to what you're doing. If you're looking at the bottle, chances are that you want to do something with it. It's not like you're driving down the road and the bottle forces itself into view like a billboard. It would be better if this form of adblocking could somehow detect if the branding was actually attached to the product and let that through, since it does double duty as branding and identification.
