True, there will be enough users that doesn't care about all of this, but there's still a non negligible part of user (and those are probably the best contributors), and more importantly moderators that will leave Reddit. It will probably disrupt the site, without all of the leaving moderators, Reddit will quickly become the wild west, and it would be really difficult for them to moderate the site themselves, there's probably users that would want to replace the leaving moderators, but not enough.

Honestly I won't care that much when it comes, because the "new" Reddit will not be the same Reddit that I loved.

I hope they'll reap what they sow tho.
