$70m is just $5m shy of their entire "subscription and advertising revenue" line item, with none of the extra cost of getting that revenue. Your back-of-the-napkin math would suggest that donations could render all of Mozilla's for profit side projects unnecessary and allow them to focus that energy exclusively on the browser. What's not to love?

You're comparing the success case of donations against the failure case of profit side projects.

As I said above, if it's a failure, fine, at least they tried. Knowing that it's possible to replace the side projects with a better model why would they not at least try?
