It's worth noting that the maintenance of the "lite" version is at some nonzero risk of burnout for its developers, ironically in part due to Mozilla being unnecessarily hostile:

https://news.ycombinator.com/item?id=41707418 - and while there's no plan yet to discontinue the Chrome MV3 compatible version, there are a million ways that this could go wrong.
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.
