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! Blocking isn't just about not seeing ads, it's about a user's freedom to set up their "user agent" to preserve their privacy online from sites that don't respect their wishes. That's a right that Google is using its market power to erode, and it's not something we should take sitting down.

Some of the anti-monopoly investigations of Google might achieve this too.
The removal of MV2 is extremely clearly Google abusing their dominant market position to line their pockets at the expense of their users.
When this goes through, there will be another EU anti-monopoly investigation just for this.
