> Short answer? Yes. Long answer? Definitely.

No one is paying for browsers. Maybe there is a market for enterprise support contracts for it, but this is not going to replace the money spigot of Google Ads. If I were to guess, Chrome "as its own business" would go bust very fast, with the staff being picked up by Microsoft (to support Edge, which basically is a Chrome fork) and Apple (to make Safari decent).

Android I'd say could survive, at least as long as it is bundled in the same entity that handles Play Store, that thing is a money printer. Without it... I'd say Samsung won't care, they already have their own marketplace and mess around in AOSP to an unholy degree, and everyone else will either attempt to fork Android like some Chinese brands did, go for Graphene or go bust like HTC.

Youtube... they probably got enough Premium subscribers now to keep the lights on, the problems are going to start when they have to separate their infrastructure. Bandwidth is still insanely expensive and at the moment they benefit a lot from Google being the top dog, able to tell even the largest ISPs "peer with us for free, or else". Without that leverage, with their own infra, bandwidth costs are going to eat them alive.
