It is a little weird how Mozilla doesn't advertise Firefox, isn't it? At least I've never seen them sponsoring anything, nor any ads. (50% of my browsing is without adblock, so I should have seen them if they exist. But maybe they do?)
Like 1M/yr spent on sponsoring 1000 videos by top tech youtubers is nothing when they have 600M/yr revenue and it would bring in a massive audience.
It's as if they're content with coasting and/or chasing even lower single digit market share?
