Gogol is part of the whatng cartel with its blink web engine, but that case is more accute with gogol because they own very dominant IP based services which apple and mozilla don't have.

There are 2 webs:

web apps, requiring a gigantic-enormously-complex(SDK included) [java|ecma]script web engines: only available from the whatng cartel, webkit (mostly apple), geeko(mozilla), blink (gogol, fork of webkit).

web sites, classic noscript/basic (x)html (simple HTML forms with <video> and <audio> elements, often with an optional simple CSS).

gogol: "You want to use my ultra-dominant online services? I will force you to use one web engine of our whatng cartel, even if they had been working decades more than fine with alternative classic noscript/basic (x)html browsers."

Remember, not so long ago, gogol was paying billions apple in order to get their browsers to default on gogol... I don't recall the amount mozilla was paid.

Don't let them fool you: they actually "work" hand in hand.

There are serial offenders on a wide spectrum.
