Fortunately, the person you were responding to wasn't making a bad faith argument, or even arguing at all, but was rather expressing a common opinion based on anticipating entirely predictable behavior.
I block ads, nuke cookies, and use old.reddit.com exclusively, but somehow I still manage to spend a lot of money on shit I don't need. Most of it was found on reddit. All of it got a google search that included "site:reddit.com" before buying. This anecdote is not unique. The fact that reddit gets $0 despite being part of my typical buyers journey is a failure of Steve Huffman, not the users.
