I try to support Mozilla (and more obscure open source projects we take for granted) through donations and subscriptions. But I never used Pocket or Fakespot.
I don’t think it should be a forced payment but I’d pay a few bucks a month for a true developer edition. The current one is essentially just the early beta for extension developers but something really developer focused with no bullshit and developer tools at the forefront. I don’t know if that’s something other people would pay for but I feel like it’s easier to shell out cash when I’m using it for work. A lot of people could probably expense it.
It likely wouldn’t replace the Google money but it’d be a start.
