From what I can tell - Drivechain might make miners more money and we don't know what they'll do with it.... Drivechains enable other things to be built on Bitcoin, that could be bad.... Drivechains are too complex because I am not a developer therefore they are scary and bad.

But it honestly is starting to seem more like subconscious protection of the LN related investments or some weird fears of the unknown with regards to the SEC claiming any namable entity who builds anything new on the protocol automatically renders it a security idk...

I don't see the drivechain critics talk bad about CTV or recursive covenants (in regards to complexity and potential for unforseen consequences...)
