- Zoom is a company that sells it's conferencing software directly, and it's the core of what they do and sell, if it's bad people don't buy it and they go bankrupt.
- Google does whatever they want since most of their money comes from ads. You don't buy Meet from them directly, it's just a small unit in a sea of thousands other things they do. If it's bad and people don't use it, or they get bored of it, they'll just throw it in the graveyard[0] and carry on...
Basically it does not matter how much talent and manpower you have, all that matters is the business model.
Google may have many clever engineers but lack focus in many products which feels half-baked.
E.g. their podcast app, music app, weather app, fit app. All feel kind of half compared to many of the dedicated alternatives.
