Mozilla could have added years ago a donation or subscription to fund the development of Firefox, but they don't want that. Mozilla wants all the money for its charitable activities instead.
There will be a time when they have no money anymore, but it's only their fault.
Although their $7 mil CEO could have found a way to handle this while not running afoul of the IRS, but she decided to play with a bunch of dead-end commercial endeavors instead. So that's on them.
Describing Mozilla's derailment as "charitable activities" is like describing the Mexican cartels as "self-help groups".
Never forget their "We need more than deplatforming".
