I agree that there's a "that's life" aspect to collateral/tradeoff. That said, I sympathize somewhat with the parent. "Done right, negative side effects are minimal" is an uncomforting statement. First, because things are often not implemented correctly. There are a lot of details and tuning that will often fail to materialize in practice. Second, because long tail usability issues can often go overlooked. The abuse->anti-abuse feedback loop is pretty tight. Abuse gets identified and counteracted. The anti-abuse-> UX problems loop tends to be noticeably looser. Often, it's just aggregates (revenue/AUD/etc).
