They also rely on that industry for keeping their lights on.

Approximately 85% and 81% of Mozilla’s revenues from customers with contracts were derived from one customer for the years ended December 31, 2023 and 2022, respectively. Receivables from that one customer represented 70% and 64% of the December 31, 2023 and 2022 outstanding receivables, respectively.

That customer is Google making Google search the default on Firefox.

They also keep hiring useless venture capital CEOs and keep increasing their pay, while firing workers at the same time.

Nobody is telling you to stop using Firefox, but pretending that Mozilla is some kind of savior saint is just false.
