We should all probably start donating to Firefox. Isn’t Google their main source of income?
There might come a time when they prefer to gut Firefox, forcing Mozilla to either reject uBlock Origin or die (or they could simply pull the plug on funding knowing they’ll earn more when people go back to Chrome-based browsers)
Even if they did so, isn’t Firefox entirely open source? At least their work could be forked (though I agree if they don’t have the resources, hardly anyone else could make it)
