That is true, but what is also true is that a few products are currently sucking all of the air out of the system, preventing new entrants from encroaching on the incumbents territory.
Maps, Search and Youtube all serve the Google Search business. Any new ad-supported entrant, by necessity, also has to serve the Google Search business.
If the Google Search Business is crippled, there are only good things that can result from that. I don't see a downside to making Google Search unprofitable due to smart ad-blockers. (I welcome hypothetical scenarios in which the Search Business being limited due to ad-blockers has bad unintended consequences).
Unrelated: I don't understand why this comment is modded so low that I can barely see it? It is not in any way controversial and can be (and is, above) rationally debated.
