A "little indie developer" hasn't been able to write a web browser in several decades. An implementation of 2005-era CSS and JS would be a complex task surely requiring a fairly sizable team to implement.
The fact is, all three major browser implementations are open-source and that has allowed any company to come in and release or embed their own browser with minimal effort.
