isn't this same behaviour when you open Google, they try to sell you a Chrome?
Just cross selling their products using the medium they own.
Just cross selling their products using the medium they own.
They are deliberately interfering with your choice of using someone else's web browser, and they are doing so for reasons that have absolutely nothing to do with the functional considerations of their product.
In a normal world this would attract legal scrutiny given their history (and in the EU, does).
The Google behaviour you're talking about is using a typically free service as a marketing channel. That is to me not quite in the same category.
If there was evidence that Google was arbitrarily hobbling non-Chrome browsers when using Google's online products (and I am in no way saying there isn't!!) then _that_ would be comparable, I think?
Hobbled Firefox on YouTube via ShadowDOM and polyfill? Hobbled internet explorer on windows mobile for both YouTube and google maps.
Google on iOS and android does the same shitty nonsense as Microsoft here.
For starters, Windows is an operating system, not a website contained in browser. There are many differences in usage, privacy, security, etc.
Also, unlike a website or browser, if you got fed up and decide to leave, then changing the OS can range from challenging to practically impossible (outside your control).
