Firefox has been viable as a standalone product for over a decade because Google pays for being the default search engine. This is roughly viable with Chrome being around, it would be even more viable if Chrome was not around.
However, Mozilla doesn't have a massive userbase like that, which leads me to suspect that Google only pays Mozilla to stave off pressure form regulators who would otherwise accuse them of having a monopoly on browsers.
You can't compete with Chrome when your primary merit is simply not being Google. Forcing Google to spin-off Chrome should have been done earlier though, before Microsoft had a stake on the engine. Now additional steps need to be taken to ensure that spinning off Chrome will not actually kill competition; with an independent Chrome, we can count on Google cutting down on Mozilla's funding since Google wouldn't be any longer in danger of being ruled as a browser monopoly.
I wonder if this means that we should all start starting dating app companies, given that apparently it's a guaranteed sale if you can attract enough users. We could start the "match group group," stamping out standardized dating apps and putting proven amounts of brand-building effort into each one, and selling them to Match Group at a repeatable price.
Google seems iffier, since Chrome at least would never be viable as a standalone product (as the fates of Mozilla and Opera have taught us).
Totally agree that Match group is an interesting under-the-radar one. It's shocking how much of the market they control with all their "competing" apps.
