My only long-term hope for this space is that a nonzero segment of congressional representatives have had ad blockers installed by their aides, realize that their experience online takes a nosedive when MV2 is discontinued, and calls for hearings!

That's a right that Google is using its market power to erode, and it's not something we should take sitting down.
