Almost no one can do game development as a small company without a large platform of some kind. The economies of scale are just too much for small indie dev style game studios to overcome. Speaking as someone that was an indie dev and has been around the game industry for 20 years. I highly doubt that is going to change anytime soon. Webassembly certainly won't fix that issue. I'm not sure what that comment has to do with the subject. With Webassembly you won't have to pay for server side gpu but you will have to pay for discovery, hosting/bandwidth, payment, likely some form of advertising, and some level of support. There is no free lunch and large platforms will nearly always win for software distribution.
