Earlier quoted context omitted.
Oh, Apple is a brutal dictatorship that doesn't share anything? That's fine. Oh, Google, you're willing to share almost everything with anyone for free, but you want to put terms on that? Hey, here's a giant fine. I just don't understand the logic of this at all.
The logic is that you're not allowed to use your position in one marked to gain influence in another. Google knows that most manufacturer needs their devices to ship with the Play Store, because that's where the apps are and smartphone without apps are useless. But they use the Play Store as leverage, forcing manufactures to also ship Chrome, rather than Opera, Firefox or their own browser and that's the bit that is…
The same goes for Samsung and its own browser, simply called "Internet": people often have heard of Google Chrome but won't go looking if there's a working "internet button" right in front of them. Other vendors use the same trick.
Personally, I would think this is a good thing as it takes away some of the monopoly Google has, if Samsung etc. would just give their browsers regular updates through the Play Store/their own app store (latest version I can find on the Play Store still uses Chrome 59).
There is no technical reason to install the Google app or to install Chrome. Vendors can easily install their own WebKit/Blink engines for all the WebView/technical requirements (as seen by alternative ROMs) and the Google app can be deleted without affecting the other Play Services.
I think this is a ploy to prevent companies like Microsoft from coming with their own ROMs that focuses on Microsoft applications (Cortana, Bing, Edge mobile, Outlook, Microsoft Office etc., MS have a near complete stack of applications for Android) without offering any pre-installed competition like Google does.
