Mozilla is an advertising company now

Let’s imagine they do. Let’s imagine they start gaining on Chrome. What do you imagine would happen? One possibility is Google pulls out of their deal with Mozilla and Mozilla runs out of money in like 6 to 12 months. That’s the end of all browser competition.

Mozilla corp. tries to diversify its income sources. I understand why it’s being criticised, most of their attempts look like lack of focus and not many of them are awefully successful.

But also consider that if all active Firefox users donated like $3/y to Mozilla it would cover Google’s $450m/y. Users would become the primary source of income for Mozilla and then Mozilla would listen more to users rather than try balancing what users want (to maintain user base) and what Google and other businesses want (to maintain revenue stream). So your contrubion of only complains on the internet and exactly $0 is what makes Mozilla buy ad companies.
