Google literally sends your browsing habits from pages visited to mouse movements to their servers where they link it with your other Google info like Gmail, Google Calendar, and Google Maps GPS tracking via your phone. Google products “leak” all the users data back to the mothership as a feature. And Chrome users tend to use a lot of random extensions which means the data usually leaks to a lot of unknown third parties as well (see DataSpii for one example which effected millions of Chrome and Firefox users)
So yes let’s expect higher standards from all browser developers. But realistically Apple likely fixed the bug or has a very good reason why it’s difficult to entirely patch yet. Google has had many extended data leaks as well but they actually build tools to gather your data up in the first place which makes it that much riskier should it get stolen or misused by Google or Google employees.
It's a security bug that leaks information about the user. It reduces privacy for the user to any website they visit. Chrome and Firefox fix these security bugs immediately upon learning about them. Safari does not because it had hyped ITP and is more interested in security theater, which makes for great marketing, than actual security.
I don't know why you are trying to redirect the conversation to services that can be accessed from any browser. The topic of discussion is which browsers are more secure and offer better privacy.
Guess what story popped up when I logged in today? https://www.tomsguide.com/news/chrome-google-site-data-speci...
“Chrome won't clear your Google and YouTube data — even if you tell it to
Browser retains site data in defiance of privacy settings”
Every week there is a new scandal with Chrome privacy and usually it’s Google to blame and not a bug. I’m sure they’ll tell us this was another honest mistake that tracked billions of people for ten years but NEXT time they’ll put our privacy first. Meanwhile we all know our data has been the goal since day one and Google Chrome is the Trojan Horse to get the tracking onto our computer
The particular issue mentioned here turned out to be a bug that affects more than YouTube and Google. https://bugs.chromium.org/p/chromium/issues/detail?id=127340
