Right I get google make money from ads
Yet that doesn’t explain in the current market with google giving their OS away for free then how is any startup company going to be able to compete with that because with google doing that they are basically squashing their competition.
See it this way.
Usain Bolt was at the absolute top of his game when he was still actively competing. I don't hear any of his competitors claiming that they ought to be given a 30-second head start in order to stand a chance of winning. I guess it sucks to have been born during his time, but it is what it is.
I have also been delving in the vTuber rabbit hole of late, and one observation I have made is that the ones with more active viewers are those who were active many years ago when the concept of being a virtual streamer was still a fairly new and novel one. Today, it feels like the space is pretty saturated, with new entrants struggling to grow an audience and having to contend with viewership in the low hundreds when everyone else appears to have already latched on to an existing streamer. In short, there just isn't much of the pie left to fight over.
The same can be said for the video streaming space. Currently, it seems like only Netflix is profitable (and only after more than a decade in business), while every other service is making huge losses. Only Disney, Apple and Amazon seem like they have the resources to keep funding the creation of new content indefinitely.
The truth of the matter is that the reason why Google is so dominant goes a lot deeper than them simply giving away their version of Android for free, and I suspect that you are simply choosing to not see it. You think that the entire problem is caused by Google and Apple choosing not to share their technology, but the real answer, I feel, is a lot more nuanced than that.
There's the services like google maps which Google also makes available for free, and which they can choose to not make available on competing platforms (like windows phone). There's the App Store (which is more a developer problem than a google one, because even back when Microsoft was trying to make Windows phone a thing, developers famously decided to not release apps for it at all). There's the stark truth that it's no longer enough to just release a smartphone in today's day and age and expect it to be enough. You have to come up with your own ecosystem and it's not something you can create from scratch in a single day.
And for all we know, even if a new entrant releases a third smartphone OS, why would any smartphone OEM want to adopt it over Android when again, the former would likely have no ecosystem supporting it? Why would any consumer want to buy said smartphone over the more established brands like Samsung or the iPhone?
You are asking a lot of "what if" questions, to a problem that does not have a single straightforward answer or solution. Companies like Apple and Google did not arrive at their current dominant position by chance. Yes, they started off on the right foot with a great product, but they have also spent billions of dollars over the years improving on said product while also building a formidable ecosystem around it. Apple has also spent the better part of a decade building up their supply chain in China. Apple also had to bank on a fervent user base from their Mac days. And it didn't happen overnight. Every percentage of market share iOS and Android enjoy today, they fought tooth and nail and earned from the likes of Nokia, Blackberry, Windows Phone, even webOS and each other.
Why then do you feel like a new upstart is entitled to dethrone the incumbents without having had any of their accomplishments or their investments to show for it? Especially when Apple and Google have not been resting on their laurels and continue to improve on their product offerings every year?
Which is also why I find it ironic in a sense, that after all these years, we may finally have a new competitor to Google (openAI), and the first instinct is for everybody to call for AI to be regulated and to preserve the status quo (which will serve to only further entrench Google's dominance). ¯\_(ツ)_/¯
