When Opera announced the intention to follow Google to Webkit, and later, to Blink Engine, many people cried in social media about how we where closing to an IE-like time where standards are adopted only when the engine maker decided to support it, where the engine's bugs and flaws became de-facto standards and no one could do nothing to change it.

The only safe route to allow the web to remain free and grant new developers a chance to re-imagine the browser, allow Opera Software to focus on the experience, and keep the engine field open, is to allow everyone access to Presto, maybe allowing only non-commercial usage, and charging a fee to commercial usage.
