Congrats on all the work here. Browser streaming isn't easy stuff!
Pricing is a good example of something that most people are intuitively wrong about. What you think people will pay and what people actually will pay are rarely congruent, and most of the time people guess far too low. Literally every bit of advice and writing about pricing I've ever read boils down to "Charge more than what feels right; you'll be surprised at how high you can go before you lose customers."
Apple keeps applying this strategy since 1990s.
Tesla bootstrapped itself off $80k cars, and only now is expanding to the "reasonable" $30k market segment.
You may not need everyone jump on your service just yet, you can start with the most needing it who are moneyed. Then you expand, economies of scale kick in, and you can introduce lower and lower price tiers, and people enjoy falling prices and getting a bargain.
Perhaps their solution has something specific to the browser which allows them to do it really fast and cost effective. Eg. Sending just diffs of DOM to the client.
